it may be the case (if Mermaids is anything to go by) that those organisations have weaker safeguarding.
Mermaids, for example, actively celebrates 'queer culture' which included the trustee who gave a speech on the need to normalise paedophilia. Many of the contributors to 'queer culture' have a record of challenge with respecting other people's boundaries, consent etc and it's odd how many have ended up disappearing under a cloud when police action became a possibility. Mermaid, in the throas of their 5th safeguarding catastrophe (come to light so far) were saying that safeguarding was transphobic before their interesting CEO moved on to pastures new.
It's not a bug. It's a feature.
Homosexual people (I use that word for myself now since 'lesbian' means something quite different and is regarded as an act of aggression against males for a female person to use to describe themselves and imply their body is off limits for the male's sexual satisfaction) spent bloody decades trying to get the general public to understand that homosexuality did not mean any lower social and sexual standards of behaviour, respect for others and safety around children than hetero people had.
And now you have the ones in dog costumes with erections who want to be patted by kids while telling you 'this stunningly inappropriate breach of everyone else's consent is an integral part of being LGBT+'
Hence why 'LGBT+' no longer to many of us has anything to do with being homosexual.
