I see it happening again and again. Someone in a position of privilege says something cruel or ignorant about a group of people who are marginalized, pathologized, brutalized, or otherwise generally shit on by the dominant culture. People respond, pointing out the ways in which the things the privileged person said is hurtful or inaccurate or otherwise problematic. The privileged person complains about how political correctness is destroying freedom. And then everyone else is expected to shut the fuck up.
But, you see, that's not the way free speech works. You are absolutely permitted to say whatever you want -- I will always oppose any law that gets in the way of your doing that. But, then, I am allowed to say that what you said is fucked. And if you turn around and say that I am taking away your rights by criticizing you and I need to be quiet -- well, then, who is trying to shut down free speech?
Its kind of like the way Christians claim to be oppressed in this culture right now. Allowing people to have marriages that your church doesn't approve of doesn't stop you from practicing your religion -- nobody is requiring or expecting you to change your rules about who your clergy will and won't marry. But making laws that say that Quakers and Unitarians and Pagans aren't allowed to perform weddings that your megachurch pastor disapproves of really is curtailing religious freedom.
I don't go by the bullshit about "what this country was based on" or "what the Founding Fathers intended" -- what the Founding Fathers intended was for one group of white male landowners to be allowed to make money without paying taxes dictated by another group of white male landowners to pay off the debt from the genocidal wars waged to make both groups richer. But I am a believer in consistency. If you want to invoke freedom of speech, you need to realize that includes other people's right to call you out on bigotry.
