I'm not so sure your conclusion is sound.
For example, consider the violence progressives have been paying for.
Looking past the violence that is being encouraged, people can see flags from another nation. That fact is a cancer progressives may be called to answer for.
Consider the fact, illegal immigration is causing the most harm in black neighborhoods. Once again, Blacks are being asked to support liberal/socialist progressives without question, while at the same time, liberal/socialist progressives are encouraging illegal aliens to cross the border, and in effect, make the economic conditions for Blacks even worse. As further insult to Blacks, billions of dollars are being spent on illegal aliens, while Blacks are being left in the shadows, once again.
These are the profound realities of the Progressive Movement in general. Funded by $100's of millions from unions, Progressive Groups, and PAC's, the violence and intimidation may not concern the intellectually vacant who are already in the cage with them, but they are seen by the rest of the population as an effort to terrorize the population into silence and submission. I don't think that is a winning strategy.
