the slander that comes from those who accuse others of bigotry against some 'special group', when it's always false and supremacist oriented, may in fact be one of the causes of bigotry against that 'special group'.
the corrupt organization that profiteers off of the 'silencing' of the bigotry maybe is a main cause for people acting like bigots towards those people who never end in their false accusations and slanderous name calling of others, as if it's OK for them to be what they pretend to hate towards other people who they are deluding hate them.
