justanother "Identify in any way you want using any terms you like. Why not. But can you expect everyone to understand ace, aro, demi etc?"
While it would be silly to expect people to understand something they have never come across, it isn't silly to expect them to either try to learn about it, or just accept it (smile, nod, move on). It's not really reasonable for someone who doesn't understand something to turn round and tell someone their identity is stupid/doesn't exist/is attention seeking/is just heterosexuality.
Like, if you are white and a POC tells you you're being racist, you don't get to just say "no I'm not" because they're the ones experiencing the racism, you can say "I didn't mean to be" which is probably the case, but the end result is still the same for them.
"Do you believe you are justified in being upset if people reject these labels and don't want to use them? Can you expect the same protections as gay people have?"
I mean, if someone were to call me a lesbian as opposed to a homoromantic asexual, eh, it's fine. If they called me 'straight' I'd be more annoyed, because it's just factually inaccurate. If they told me asexuality didn't exist and I was being stupid or making it up for attention, I'd be really annoyed (although I doubt I'd do anything).
As for 'protections' I think I would already get them as asexuality is a sexual orientation which is a protected characteristic, so were I to face any discrimination on the grounds of my sexuality then I could seek recourse...if I could prove it.
myvisions that's a fairly reasonable rule, although I would encourage a more nuanced view, sometimes Tumblr posts some factual and interesting things, and sometimes Buzzfeed is full of crap lol always worth trying to fact check through other sources.
Flora I don't think that has anything to do with anything? For one, sexuality and romantic attraction can be quite fluid, for another sometimes people do just experiment or think about experimenting outside of their usual orientation. Maybe all these women are still bi, or they're not, it's fine to ID how you like.
