They're not remotely what comes into my head for that subject, and I can think of many things where freedom of speech is far more important to me than which words are used in which ways to define sex/gender/etc.
Is it possible that you too have allowed minority interest groups to convince you that trans people are the next big threat, just as gay people were decades ago, and that's why it's the first thing you think of? (Not a rhetorical question, I don't know anything about you and hopefully you're completely not transphobic! But many transphobic people don't consider that word to describe them yet do fall for and repeat explicitly transphobic agendas...)
