It appears you may be in the UK, OP, where the threat to free speech might be universal. In America, it's conservatives who have their speech threatened while liberals speak freely. Here are some examples of things leftists have said in America. Notice all of these are rather hateful comments, all of these people have powerful positions and can make those who disagree with them suffer, and yet all of these people kept their positions of power after they so openly announced these things. Free speech truly does mean freedom from consequences, no matter how hateful the speech is, if the speech is leftist:
"We have got to eliminate the gringo, and what I mean by that is if the worst comes to the worst, we have got to kill him." -- Jose Angel Gutierrez, professor, University of Texas, Arlington and founder of the La Raza Unida political party.
"Civil rights laws were not passed to protect the rights of white men and do not apply to them." -- Mary Frances Berry, Chairwoman, US Commission on Civil Rights
“Why is white america so reluctant to identify white college males as a problem population?”
Dr. Saida Grundy, a black professor at Boston University.
“Whiteness is most certainly and inevitably terror.” Zandria Robinson, assistant professor of sociology at the University of Memphis.
