Why does the LGBT community feel persecuted by the religious community, when there are perfectly non-religious reasons in other countries for feeling it isn't natural?

For instance, in other countries, like China, they don’t feel it’s natural [even though it exists] and they didn’t arrive at that conclusion because of religion.

Please don’t assume that I’m anti-LGBT because of this question – this question has been a thorn in my side for a long time. I’d like some perspective.
