That's not good enough. In real life you can't live among regular people without acknowledging someone's gayness at one point of the day or the other.
And that's what stinks about "real life", and is much more appealing about Star Trek.
Happily, around here at least, there's no pressure to "acknowledge" anybody's sexual orientation. Oh, there's always the obligatory "shrieking faggot" or two who actually desire acknowledgement, and giving it is a delight all around.

But I'd challenge you to spend, oh, a month or a year in my social circles and dig out the various perverts and freaks among my fondest friends. I might even give you a decade to make it fair. "Acknowledgement" isn't something you would run into.
There's no need to project their biases onto the characters in-universe.
Xctly. This LGBTXYZ craze is a bit akin to writing Trek stories where the heroes are all hot and bothered about dark matter or telomeres or, god forbid, chaos theory. Why should 23rd or 24th century people be the slightest bit impressed by the hot topics of the 20th or early 21st century? It's ancient and barbaric history for them, something their children's books might mention offhand the way ours may refer to Galileo Galilei or serfdom.
