I'm for keeping all "speech" on these platforms. Hate speech today may be defined different than hate speech tomorrow. Who can know? What I do know is that our freedom of speech wasn't implemented to protect people saying "please" and "thank you" or other polite words/views. Offensive speech is subjective and is exactly what our freedom of speech was meant to protect. I don't endorse offensive speech, but I certainly support everyone's right to say it. With that said, no one should confuse "right" with license.
