Depictions of disability that don't go further than the aesthetics / surface level idea of what that condition is, and that fail to actually represent disability in a meaningful (or respectful) way.

I.e: a doll with scoliosis has a back brace but no other elements of scoliosis, reducing and sanitizing the condition down to an accessory.

And they're going after the people at the top, too. Actually dealing with the source of the issue. Good stuff.

My dad tried to have a conversation about this with me but for some forsaken reason decided to open with 'some people have 'reasonable' arguments against it but are being called transphobic anyway.'

Yes. That's because they're arguing in favor of restricting people's access to resources and respect, based on unsubstantiated fearmongering. Their intentions might not be bigoted, but the result they're pushing for is.

Besides, it doesn't matter how well reasoned your argument is if you're starting from a point that you pulled out your ass and have no evidence for.
