How can the working class expect liberation from leftists/communists/etc when they favor censorship? Censorship is oppression. Sending workers into reeducation camps to think like a leftist is an antiworker thing to do.

Leftists and communists have no interest in bringing workers together to defeat the ruling class. Instead, they want to rule over workers to become the new ruling class.

In other words, leftists and communists are the enemies of the working class.
