“This time I said sodomites are notorious child molesters.”
Well, that’s going a little beyond just a normal discussion. Comments like those probably violate some rule they have regarding “hate speech” or whatever they choose to call it. Of course, those policies are never enforced against leftists and are often interpreted broadly when it comes to speech from right-wingers to the point that all criticism is considered hate, but that’s probably the reason you’re getting the bans. (Not sure if they tell you what rule you supposedly violated when they ban you on Facebook.)
They refer me to the community standards and fair enough it can be considered hate speech due to sexual orientation. Fine but then what can you say. Can you mention what happened to Sodom? In those standards though it is clear they don’t enforce the intolerance of death threats if they are uttered by Muslims. Trump needs to investigate Facebook because they have a legal duty to report death threats to authorities.
