I'm not gay, but I can guess that the problem is like being in an interracial marriage.I must be too obtuse, because when someone expresses a ridiculous opinion like that I usually just assume they're an ignorant moron and completely disregard them.
The real issue is NOT the strident, intolerant, and stupid. Those you can ignore.
But the expressions run the entire spectrum, from the hate, to the uncomfortable to the base assumptions. Relatively normal people whose opinions you respect suddenly show up with this weird blind spot. "Oh, it's okay for you, we're just sad about what you're doing to the children."
Or someone who can never be sure if her idea of Hell comes from the Bible or The Inferno suddenly spouts every scripture reference uses to promote racial purity.
Or a high school friend observes, "I always thought you were weird liking Uhura over Rand, now I see why."
It's not even how they react, as much as the fact that everywhere you go, people seem to react. How suddenly a choice you made is the most incredible thing about you, and people HAVE to notice.
And if you go into it with, you think, eyes wide open, prepared to deal with the foaming-at-the-mouth faithful, then find it's the surprise of the more subtle reactions that's wearing...
Yea, that's fair. In the converse I also notice people in situations like that expecting reactions. They just assume every single person is going to stare or grimace or something else, because it's so common. So I can see why they'd come to feel uncomfortable a lot of the time.
I can relate as I'm far from the average in a lot of respects, but mostly intellectually. When I was a kid I was labelled gifted and dominated academics. Has it's upsides, obviously, but I've spent my life feeling like an outlier, and having negligible ability to mingle with normal people (hence post-count).
