These don't happen because they're fun fashion choices. They happen because people are becoming aware. The dynamics may resemble whimsy, but it's more than aesthetics underlying.
Can we abstractly use the terms "bald," "stupid," "fat," "anemic," or "impotent" abstractly and negatively?
All describe generally disfavored conditions folks don't have much control over. Referencing that disfavor abstractly doesn't bring it into being. Ignoring it doesn't make it go away.
This isn't about awareness in my opinion. We're pretending status doesn't exist. We're assuming folks with some condition will be offended and won't be able to handle those emotions with their own agency, so we're patronizing them by carefully policing language. That is, in my opinion, as ableist as it gets.
