PC attacks free speech is when it makes it a crimial offense to say things,
"Political Correctness" is not about putting people in prison just because they are foul-mouthed, abusive, nasty people. But it might include trying not to be foul-mouthed, abusive and nasty, and it might include commenting on, disagreeing with, and criticising foul-mouthed, abusive, nasty people. Tell me why that is wrong.
I can see that the Fasctards like to make up stories for their own pleasure pretending otherwise.
