The thing is - and sorry if I'm jumping in OP - is that it's not always as simple as some are making out, because sexuality does actually colour everything.
'Just come out!' = 'Just tell everyone in your entire life that everything they perceived about you is wrong. Every day, forever.'
It's not like telling your mate you don't like digestives.
It's also an extremely personal, sometimes intrusive thing to tell someone else to do.
Also, the thing about the smaller pool of people to date. Struggle is real. See, if you're straight, there's a 95% chance that any person of the opposite sex you meet will be straight too.
Whereas if I get talking to a guy in a coffee shop, not only is there a 95% chance he won't swing my way, but there's also an ever-present risk he'll swing for me when he finds out I'm into other dudes.
What I'm saying is the idea of just clicking with someone in some random meet-cute is statistically so much lower for gay people.
Straight people tend to assume that everyone they talk to is straight, because, frankly, most people are. Numerically, that's understandable. But when you're a gay woman or man, trying to make your way in a world that's designed for people who aren't you, it can be alienating and wearing.
