Rational minds would argue that if a group is diametrically opposed to your lifestyle then you would avoid associating with that group.  Why clamor for their attention?  

In the early days of the gay rights movement the attitude of proponents was essentially that they would go their own way - All they wanted was for religious taboos to no longer be codified into law and used to regulate their lives.  It sounds fair enough, but the problem with the political left is their underlying agenda of incrementalism and their unhealthy tendencies toward moral relativism.

In other words, give them an inch and leftists will steal a mile.  They see compromise as an invitation to dominate.  Giving concessions to a leftist is the same as inviting a vampire into your house; do it once and they'll keep coming back to feed whenever they please.

The gay rights issue is a perfect example of this ugly habit.  In the 1990s the community was widely accepted in the west, the only right they didn't enjoy was to have their marriages recognized nationally.  They claimed that once that right was achieved they would ask nothing more of the Christian community or the church.  And of course, that was a lie.  

Today, gay and trans rights groups demand that all church denominations accept trans ideology and trans membership.  This includes gay and trans church leaders that teach "tolerance", mixing activist mantras into religious lessons and supporting "trans visibility".  Going their separate ways is not enough and lack of association is unacceptable.  Leftists require that their beliefs be adopted by everyone everywhere. 

The Vatican under Pope Francis has been surprisingly reticent to welcome the trans movement into the fold, despite Francis being a devout globalist on more than a few hot button issues. Earlier this year the Pope called gender ideology the 'worst danger today', noting:

'I would like to emphasize one thing: It is very important that we have this meeting, this meeting between men and women, because today the worst danger is gender ideology, which erases differences.'
