One can “not hate free speech” while also “hating what you are saying.” These are two separate things, it’s like saying “I like soda, but I don’t like pepsi.” There are other sodas, and there are other “things to say” besides racism. In this instance, tell the hypothetical person you’re talking to who said “oh you hate free speech,” “No, I’m all for free speech, and I’m also for freedom of association. I don’t like what you speak about, so I choose not to associate with you.”

Sure, in this context maybe it is a wink and a nod, but saying “free speech is a dogwhistle” and insinuating every free speech activist since Jello “Nazi Punks Fuck Off” Biafra is actually a secret right winger is patently ridiculous and it is a trend I’ve been noticing recently, and I will exercise my right to free speech to criticize the practice as you are free to ironically exercise your right to free speech by asserting that free speech is actually a dogwhistle.

To your see alsos:

“Patriot” and “Thug” I’ll give you, but “Protecting children” isn’t a “dogwhistle,” it is a manipulation tactic and it is used by all sides everywhere. Every time I hear it for any reason I am immediately suspicious of one’s motives. It is unsurprisingly effective on parents too, but since I’m not one and don’t want kids I have a pretty good immunity to it.
