My reaction to this was...what? Why?
And then I thought, am I being a bigot here, being as I’m also of a religious persuasion?
And then I thought um, no, kink is (presumably) something you do IN PRIVATE, so why on earth would it affect your rights or safety in public? If you’re gay or lesbian or bisexual in a same sex relationship there are parts of the world that are actively dangerous to you, and there are people even in countries with same sex marriage who’d be happy to beat you up.
Unless you’re fighting for your right to be kinky in public spaces, why would you add it to a campaign group?
Maybe it’s not a campaign group any more. Maybe it’s more like a social club? (Or a religion, ha.) Because if you’re British, what rights are you missing? Never mind the countries you’d be stoned to death in, let’s publicise how kinky and open minded we are!
Though I’m always wary of asking “what rights don’t [group] have in this country?” Because even if the answer is actually “none” you still sound like an MRA.
