Ok, I'm just having a rant and I know FB groups are free to set their own rules.
I've been following a fab FB group, (Home for Peculiar Artists 2), post goes up from admin saying this is a reminder, we don't allow anything Harry Potter or JKR related, if you don't know why then educate yourself. Lots of supportive replies.
I'm on the group in my real name, so I'm not going to weigh in, but it hugely fucks me off, so many people just believing lies with no dissent allowed. Just makes me think this whole thing is insurmountable.
