Actually,
having lived in Europe for over a quarter of a century, I can attest that the fabulous gene is present and active in organists here, too.
It is, however, a very very extremely different gay reality for organists in central Europe than in the US. Not nearly as segregated a group or as, queenly, taking all in all.
Nor, to be honest, anywhere near as competent musically as the Americans. I think the Americans have done a much better job of integrating style, technique and new technologies to re-interpret both secular and liturgical music as well as jazz. Europeans tend to be very narrowly focused. This might have to do, especially in Austria and Germany, with the very strict certifications and classes which the two most prominent religious denominations have successfully continued over from the 19th century.
Yeah, I have a friend who is an organist and through Andy know several organists and have had the opportunity to listen to several hundred concerts through the years.
