Well, I don't agree that Christians are being persecuted in the UK for starters.
Catholicism - or rather, a particular parish - was a driving force in an ex-acquaintance transing her lesbian dd. There was so much gnashing of teeth in the family when the dd come out as lesbian, much counselling by the parish priest as to how dd didn't have to act on her disordered feelings - and strangely, when the dd transed into a transboy, quiet. All objections went away. Because he wasn't gay anymore! A win for our Lord Jesus Christ and Saviour.
However, Catholicism itself doesn't believe in 'born in the wrong body' mutable sex stuff. It's the homophobia (stronger in some parts of the Church than others) which is causing the promotion of trans.
(Acquaintance is ex since I said 'oh, do you think your dd could be dealing with a lot of homophobia ? And she cut me dead for suggesting her child was gay. Even though child had come out as lesbian. And was a female exclusively attracted to other females. It was a startling example to me of the role homophobia plays in people's transition...sorry, tangent.)
