Does Facebook ban controversial statements such as “children should be given hormone blocking therapy if they request it, regardless of the wishes of their parents, even if it sterilizes them” or “transgender women should be allowed to go to/volunteer at battered women’s shelters”. Espousing the opposing viewpoint is a fast track to getting banned from Twitter/Facebook or wherever else.

Note I’m not making a judgement about these statements, merely using them as examples of things that absolutely won’t get you kicked off of Facebook for advocating.
