So gay is not child friendly? Than I guess straight, lesbian, transgender, bisexual, asexual, male, and female should all be removed too. To say that gay is not 'child friendly' is to says that gays are not an accepted part of society which I believe we can now say they are. It was most likely removed do to it being used as an offencive term.
As for the rest of the thread, they were being spammed, used as offensive terms, or associated with any of those things. If Hillary Clinton was creating radical controversy it too would most likely be removed.
