On the two stories you talked about:

1. They weren’t entitled to get their demands, and protesting on private property makes them subject to getting kicked off that property. I don’t agree with their methods; if the underlying message was about racial justice, they chose a poor way to express it.
2. The head of the school had to consider all sides of that issue — including the side of “if we keep associating with this person, the shit will hit the fan, and people might get hurt as a result”. The lawyer in question was not “silenced”; they can still say whatever they want. The lawyer in question was not prevented from doing their job; if they still chose to defend Weinstein, they were allowed to do so. But here’s a question I’d like to see you answer: Yes or no — should the school have forced students uncomfortable in the presence of someone who was planning on defending a rapist in court to associate with that someone?

You don’t think Mob’s can stifle free speech with intimidation??

They can. But that doesn’t mean they always succeed in trying, or that they always attempt to stifle speech through intimidation.

Isn’t that supposedly what Antifa & BLM are about – for change thru intimidation?

Three things.

1. “Antifa” is shorthand for “antifascism” or “antifascist”; there is no organized “antifa” group, which is to say there is no organized group that tries to control or claims to represent the messaging and the actions of all antifascists within the United States.
2. “Black Lives Matter” is a movement dedicated to racial justice by way of reforms in police and government; while there is a “Black Lives Matter” organization, it does not speak for all people who consider themselves part of the movement, and the movement as a whole is not seeking “revenge” or “vengeance” or whatever other boogeyman you have dreamed up in your head.
3. If by “intimidation” you mean “using protests to put pressure on lawmakers to enact change”? Yeah, sure, sounds about right. (Lawmakers don’t have to change shit based on protests, by the by.)

Why else protest and riot — why assault others, why burn down their own neighborhoods.

People protest because something in society has marked a breaking point for enough people to protest in favor of changing that something. In the case of the current ongoing protests for racial justice, that was the murder of George Floyd (an unarmed Black man) at the hands of the police. The broader goal of the protests is to enact reforms within police departments that focus on both racial justice and funding other social systems that are better equipped to handle certain situations (e.g., mental health facilities).

As far as riots are concerned, I’ll flip the script on your little “I’mma quote Black people in front of this dumbass White boy and watch him squirm” trick with a quote from MLK: “Certain conditions continue to exist in our society, which must be condemned as vigorously as we condemn riots. But in the final analysis, a riot is the language of the unheard. And what is it that America has failed to hear? It has failed to hear that the plight of the Negro poor has worsened over the last few years. It has failed to hear that the promises of freedom and justice have not been met. And it has failed to hear that large segments of white society are more concerned about tranquility and the status quo than about justice, equality and humanity. And so in a real sense our nation’s summers of riots are caused by our nation’s winters of delay. And as long as America postpones justice, we stand in the position of having these recurrences of violence and riots over and over again. Social justice and progress are the absolute guarantors of riot prevention.”

Better yet – 2013 – .77 lives per 100k blacks killed by whites, 53.9 lives per 100k blacks killed by blacks. Yet riots and destruction of black owned properties is the norm.. god help those who disagree.

The “Black-on-Black crime” argument is a racist deflection; shame on you for using it.

It’s all about power and intimidation – the democratic/progressive left is out of power, the want it back. They don’t care who they walk on to get it. The fanatic right is the same way but don’t riot in mass.. Different tactics – same desire.

Democrats are not “progressive”, at least not as a party. Hell, the party isn’t even left-of-center; it’s closer to the center than the GOP, but it sure as hell isn’t to the left of anything.

And of course Democrats want power. The key difference between the Democrats and the Republicans in this regard is who they (claim to) want to help with that power. Both sides are going to help rich people stay rich/get richer; let’s get that out of the way. But Democrats at least pay lip service to the idea that their party wants racial justice, equality under the law for all people, and improving the social safety net. Republicans cater near-exclusively to White people (especially Christian evangelicals), oppose equal rights for queer people, and have tried to dismantle one of the cornerstones of the American social safety net (i.e., Social Security).

And as for the methods used to obtain power? Well, I don’t see Democrats vaguely supporting (or at least outright refusing to denounce) right-wing militias, or gerrymandering districts to keep power in state governments, or doing everything possible to disenfranchise as many people as possible (especially Black people) as a way of tipping power toward certain groups of voters. That shit is all on Republicans. I mean, not once did Obama say he had no faith in mail-in voting, nor did he encourage people to try voting twice, nor did he ever cast doubt upon the results of either of the elections he won before the election even happened. Compare that to what Trump has done in the past few months on that front — and note the lack of pushback from the GOP at large — then tell me the “tactics” of the Democrats are intended to keep Republicans from ever achieving, let alone retaining, power at any level of government in the United States.

If you’re trying to convince me that Democrats are evil leftist anarchist communist bastard-coated sons of bitches who want to destroy the country by getting rid of religion or legalizing riots or whatever other ridiculous-ass QAnon-level collective delusion bullshit you want to throw in my face, you’re not doing a good job of it.
