The implication that some want to exclude gay or GNC children from their schools is horrible Yes, but that is what some religions do! They are not modernised, they are unreconstructed and if it ain't in the holy text of choice, it doesn't exit and won't be tolerated!
Nonetheless religion is a protected characteristic and when social mores and developing freedoms come into conflict with any religion there will be fireworks, lots of shouting, lots of nastiness and bigotry, usually from all sides involved.
Like you (I am assuming), Errol I don't 'do' religion at all, but can still see where the conflicts are and what is most likely to happen.
