Just surfed in here due to looking something up in Google.
As an anarchist, shouldn't you be thinking for yourself and not worrying about groupthink political correctness imposed by social engineers and the sheep who obey their diktats of what is or is not acceptable to to say or think? Seriously, express what you think and let the chips fall where they may. It will give you tremendous self respect.
Islam is not a race and there is nothing racist in criticizing or outright attacking it. It doesn't matter what it's intertwined with (correctly or incorrectly). Hell, even if it were exclusive to a race race , so what? Do Jews who claim to be a race, but are not, make you ckeck yourself when critiicizing Israel or Judaism? That's what they want. Antisemite, Islamaphobe, homophobe, racist, nativist, Nazi, commie, yada yada yada are all weapons of the thought police to shut down freedom of speech and thought which any self respecting anarchist should claim as an absolute right. If whatever you express is due to flawed information, it is only through honest and open communication that will develop new opinions (we are free to change our minds). If you are right, all the better.
Don't fall for the mind control. Fuck the thought police. You think what you think so express yourself. It's your right.
