Not a rant against religion Musket.
The pointy hat reference makes it specific to Christian churches, who of all churches have no problem with sexuality.
All congregations have openly gay couples, and we have gay priests and bishops.
The Methodist church I often attend has its second gay minister in a row.
You will not find such acceptance in,say, Islam.
The problem arises I think for some people with the concept of marriage.
It is an ancient cultural tradition that predates religions.
That is not to say it must never change, but making such a huge change to such a fundamental, deeply rooted cultural tradition will not be accepted by all people overnight.
