I'm not really part of the LGBTQ+ community, just a (mostly) straight guy who's subbed here so I can experience other viewpoints and help grow my own understanding, so take what I say as you will, but ultimately it boils down to:

It doesn't matter.

It doesn't matter to you, the casual observer, what other consenting adults are doing. Seriously, it's not your story, so why bother trying to insert yourself into it? Say you see a couple of guys holding hands in the street; how long are you going to hold onto that memory of them? Realistically, they'll walk by and within ten minutes you'll have forgotten they exist, so why let yourself notice them in the first place? Or more to the point, why assign any kind of morality to them?

As a society, I think we could be far better at letting people just live their lives without assigning our own thoughts and emotions onto them. We don't have their lived experience, so we shouldn't get upset when they don't conform to our internal rulebook.

But that can be hard to do when we as a species are wired to make quick assessments. Those quick assessments have helped us to evolve to where we currently are, it helped our ancestors rapidly figure out who could be trusted, whether an animal was likely to try and eat us, whether our food could poison us. But none of that makes any sense when it comes to looking at a consenting couple living their lives in public, and immediately placing them in an 'undesirable' box.

All you can do is what you've done here; engage with people from different backgrounds, and try to learn to understand that, regardless of who they have sex with (or not), or whether their outward look conforms to whatever genitals you suspect they have, they're just people trying to live their lives and be left alone.
