My posts got deleted for "hate speech" (containing nothing of the sort). I appealed those deletions and then they changed their mind and said they were deleted due to their "Be Nice, Be Respectful policy".
Long story short, if someone reports you for hate speech, your posts are quickly deleted even if they contain nothing of the sort. Even if you are civil, your posts will still be deleted. It doesn't matter if your argument lays out a solid foundation based on logical points, just disagreeing with someone is a violation of Quora policy.
