No one should be persecuted for their beliefs, no matter how fucked up they are.
Really? So if you employ a dude who tweets that, although he has never done so and never will, he thinks it's ok to rape women if they are dressed like a slut, you're not allowed to fire him? Because if you do, you're persecuting him for his fucked up beliefs.

No, I'm sorry, I do not have to tolerate batshitism.
