Glad to know we're in a space that allows representation for everyone
Not LGBTQ myself, but I firmly support all human (and undead!) rights.
That said, I'm curious how gender/sex is even handled in Lore. I think that's something worthy of discussion in the sense that undead generally don't reproduce sexually, so the notion of genitals and gender identity seem like they are pretty much completely cosmetic in a society that (assumedly) doesn't sexually reproduce, meaning, if everyone is asexually able to reproduce, or not reproduce at all (say like a lich) then it seems like the whole concept of gender/sex is ultimately pointless in their society (unless this is included in the lore somewhere).
IE, a vampire, lich, banshee, etc. with X bio parts (male, female or hemaphroditic) is just as likely to be a greater or lesser threat (IE, raw power tends to be the mitigating factor, thus establishing the individual being far more important rather than gender stereotype) and with that out of the equation it seems more like gender is irrelevant except in the case for those that wish to cling to notions of their former humanity. This also gets completely turned on it's head when you consider that some of these beings may be able to shape shift in humanoid appearance, and thus potentially swap gender representation at will.
From a cosmetic sales perspective that's also a huge boon to Apocalypse, being that you can sell alt models as well as skins for said models, thereby allowing people to shift gender identity without needing to swap characters/accounts, which is sure to increase potential sales. From the player perspective this also opens up lots of roleplay opportunities, not just for transgender players, but also for those that might seek to use these concepts as a form of subterfuge (IE, X NPC is more fond of Y presentation, swap into a form that is best suited to negotiate with them).
Exactly how vampires and the other archetypes reproduce I'm sure is something that likely has to come up in the lore at some point (ie how a vampire is turned). I think the only version we know of that is somewhat concrete is the liches in the sense that they don't reproduce at all but are rather, generally speaking, self created.
I could see an argument for vampires possibly favoring feminine things, given that their progenitor, the red lady, is at least feminine in representation, but I feel like when you live eternally these things cease to be relevant at all at a certain point other than being potentially poetically symbolic.
