Freedom of speech means defending someone's right to say things you find absolutely fucking ridiculous. But it doesn't mean you're obligated to stand beside them while they say it. When a Facebook post appears to take aim at my identity and the woman I'm going to marry, the abstract principles of liberty suddenly become personal. You don't have to agree with me, understand me, or even like me. But don't confuse your right to speak with my obligation to stand there and take it.
