My friend’s teenage son leased my horse for a bit, and he showed her in English events at 4-H (fun group, not the highest caliber riding). He took lessons from really great area h/j trainers and dressage trainers, and did great in his classes, but the boys picked on him as being gay - bullying people for that is ridiculous, obviously, and in this case, the boy was not gay! Well, he got into bull riding at the local rodeo. And the guy at the local Western store told him the English riders are the best bull riders because of their English training. When he started winning in bull riding, the kids stopped picking on him. And his mom and I had a laugh - in his last show with my mare, he had a gaggle of young girls following him around, while he showed English during the day and rode bulls in the evening:)
Anyway, sad but true stigma on orientation of male riders in the US, but the stereotype is based on what seem to be real percentages. Not sure why since equestrian sport derives from military training? I don’t know if the perception pushes straight men away from the sport(s)? But I’ve heard the saying quite often that most English riders (all disciplines) are either gay, married, or both…
