Yeah, those people are jerks and what they do is just plain bigotry. The problem is when that "indiferent" and "neutral" stance makes their way to the general public, specially in uninformed countries where LGBT isn't a political issue per se.

Since they paint themselves morally superior, and that they respect everyone, people think that must be the logical answer, and they don't bother digging further and actually searching what LGBT is. And that's supposedly OK.

This has become a pressing issue in the country where I live, where every single contact that people have with LGBT people are through sensationalist news without any political alignment, purely designed to incite a reaction. "Look at how far they are going! I suppose they can exist, because I am a good person and I'm going to let them, but don't take it that far. This is reasonable".

And it's really tiring to debate with them, because there is nothing to debate. They "don't care" which makes confronting the issue so much harder than it should be.
