Are you saying that you don't care whether or not the way the rulebooks depict the D&D gameworld includes you? Or are you saying that you don't care whether or not it includes others?Not to everyone. To you, most certianly. To me, not as much.Being inclusive matters.
I ask, because there are some people who have clearly always been included in the gameworld. Traditionally "masculine" white heterosexual men are one such sort of people, with either the fighter or the wizard as their class archetype and the random harlot table as a pseudo-pornographic pandering to them; traditionally "feminine" women, with MUs as their archetype, are another (in the AD&D PHB she's called "Filmar, the mistress of magic" - p 7); the Morgan Ironwolf-type somewhat "masculine" woman is yet another.
And what I think [MENTION=6748898]ad_hoc[/MENTION] is pointing to is the increased scope of inclusion beyond these sorts of people to include others.
There seems to be a certain sort of selfishness in setting the boundary of inclusion that one cares about at oneself; whereas it would be a different thing (resignation? indifference?) to be happy with the rulebooks even though the fiction they depict doesn't seem to include oneself. And when posters say they don't care about inclusion it's often not clear which of these two positions they are adopting.
I don't think it's going to destroy D&D to have characters in the gameworld who don't gender identify; or to have (say) Morgan Ironwolf rather than Conan be the love interest of the princess; or to have halflings wearing cornrows.If you want to actually destroy D&D go ahead and keep pushing the "progressive intersectionality" cultural Marxism as the core tenet of the game.
I have GMed with a black PC (in the sense of belonging to the gameworld's equivalent of the African diaspora) in a culturally European context; and with a PC was of uncertain, but probably gay, sexuality - though, given the cultural norms of the setting, perhaps resigned to a heterosexual marriage for political reasons. Things of this sort don't contribute to the destruction of D&D, as best I can tell - given that they are episodes of FRPGing, they contribute to its flourishing!
There's also not much connection between any of these things and Marxism ("cultural" or otherwise).
