and gay is (has become) umbrella term for everything that's not cisgender / straight. I'm transgender and assexual. I'm gay. I'm queer. I'm LGBTQ+. Sou viade, poha
No, it really isn’t. Gay is a type of slang for homosexual, or attracted to the same gender and specifically the same gender, and most trans and bi don’t classify as gay. Hell, if somebody told you they were bi, and then you said they are gay, they would get annoyed, because those are two different things.
They make this distinction IN THIS SPECIFIC MANGA, where they point out the discrepancies between being gay and being transgender.
It does kind of depend on the person and community they're in as well?
Sometimes. As a Lesbian myself I regularly scream out "I'm too gay for this!" but that's mostly used more like a verb??? (I dunno it's late) On the topic of someone telling you they're gay, it really doesn't matter if they are a lesbian or what unless they're bi just due to how the word is handled. If a girl tells you she's gay, you know what she means. Alot of the ace/aro people I know say they're gay on a regular basis just because they like someone aesthetically. Around other queer people mostly but ehhh
TL;DR
It kinda works and is used in that way?
I wrote to much lol
This might not make sense either haha
