Somehow i did not remember greyhawk looking like that either:
You have to be a special kind of stupid to think that an adventurer in a high fantasy setting would ever be confined to a wheelchair or transgender. It's almost like any of these designers and artists have never bothered to read their list of spells or gone through the magic items table. There's a various magical means to fix crippling injuries and several ways to actually change your gender that have been in Dungeons & Dragons since AD&D E1, though most of the gender change stuff was considered a curse.
It also makes absolutely no sense why someone that is confined to a wheelchair would decide to be a "general" adventurer. How many people in a wheelchair decide to be a high rise window washer? How many people in a wheelchair work at Sea World training orcas? Or any job dealing directly with dangerous wild animals? Probably none considering the increased level of danger that would involve with those jobs and not having working legs. There's also no way someone designing a dungeon to keep adventurers out or kill them would put fucking wheelchair ramps in them. How about the parts of dungeons that are partially submerged? There's also no way that every cave where some monster is holed up in would be handicap accessible. There's also no deep, unkempt forest out there that grew in accordance with wheelchairs in mind.
Also, enjoy those Transmute spells, Mr. Wheelchair guy. Or Heat Metal. Heck, enjoy Grease on an inclined surface. Enjoy those bigoted Rust Monsters.
WotC has gone full retard on this. You can't stop and think about any of this inclusion shit for more than three minutes and not realize how incredibly stupid it is.
