It seems to come from this organisation: www.lgbdefence.org/ which must be a little like LGBA? Any Australian or NZ MNers know?
For UK MNers, I think this could be a useful resource when questioning your MP candidates. Because look - it has happened. It's what will be cemented into our laws if we don't continue the pushback.
