To be very clear, in my opinion, Jews should not be gassed (or otherwise murdered), and not all trans people are pedophiles (I don't know the stats, but I'd guess they're about the same as the rest of the population).
Anyone who disagrees on the preceding two points has every right to openly speak their mind in a free society. And whereas their free speech rights are our own free speech rights, we must defend their right to freely state their opinions in all public forums. Free speech is not for ideas we like, but precisely for the ideas we dislike.
