...with rights for all workers that today it would be unthinkable to even question? Or worse, women's suffrage? Or rights for people of color?

There's no such thing as a (successful) social movement that doesn't employ some amount of violence - the police and the state more generally simply won't allow it.

And this folks is why police infiltration in black blocs is so effective.

You've seen how it works out, that's correct. It works out with five day work weeks, sick leave, ban on child labor etc etc.

All social progress resulted from the threat of violence. It is the only mechanism though which the capitalist class can be convinced to make even the smallest concession.

A the way we do that is to declare that someone is a communist (whether or not they are), then equate communism to terrorism, then treat it with McCarthyism or Napalm.

How's the boot?

It's even more laughable the idea of people protesting for working conditions to be deemed as "communists"

I see you don’t understand what communism means. We’re talking about socialism here. Don’t let fear of what you haven’t bothered to learn rule your life.
