I might be misreading this, but the show isn't making his sexuality the contention point, it's the people commenting on the show online. It has been roughly 5 minutes total (I haven't counted tbh) they dedicate to him and Kyle.
In the show, it's his desire to be a healer and embrace Federation science that causes tension with his family. Of that, I'd argue his family was visibly more angry about him embracing the Federation.
My only hope is the writers are competent enough to see through the numerous subplots they're weaving in a way that isn't too handwavy or drag too many of them them out across seasons.
