You're assuming that there has been some type of free speech censorship. You're also, ala Lush Rumbauh and Mark Levin, that there's some type of Marxism afoot in liberal politics which just on its surface is a baseless assertion/ conspiracy theory that plays on the ignorance and emotional hyperbole of people such as yourself. If you are going to charge that, then you have to successfully link to Marx or his philosophy and show where the Democrats are using said philosophy as a platform or technique.
The censorship isn’t an assumption—it’s a reality. It’s just not a free speech issue in a formal sense because the government isn’t involved. And again, there was a day when actual liberals wouldn’t tolerate it. But that’s the point, liberals have become leftists/‘progressives’/Marxists.
