As far has places calling things in the gray area "hate speech", I think they're trying to be safe by erring on the side of not allowing hate speech. It's their platform, I don't see much abuse, so I don't have a problem with it.
Candice Owens did lie and distort the truth, I don't know specifically about the GoFundMe because I didn't see it, but I have heard her lie and distort many time.
