Looks like you have no idea what communism really is.
My point was, restricting free speech is indeed part of communism, but be careful before judging the system in relations to other systems based on that small piece of information. It's easy to start spewing "communism = evil" because we've been told so many times, and just use any small piece of information to justify our position, rather than having a hard look, not only at communism, but all the systems in place, both their theory and applications.
Depends. Is your country trying to restrict even democratic socialists, respectful of human rights, from operating openly? Does your country use infiltration and assassination to grind its Left into dust? If so, you may just have to deal with the tankie communists.
That's more of a general European rhetoric. We (unfortunately) don't have free speech even in democratic capitalism!
