It’s not a bad thing if we decide bodily autonomy isn’t the highest standard and that it’s significantly more accurate than self decision.
The trans community is rightfully nervous about diagnostic criteria because they’ve been used really badly against us. Like 15 years ago it was common to not be allowed to transition if you had the wrong sexual orientation (we’re pretty evenly split between straight, bi, and gay, so between 1/3-2/3 were rejected) as well as real life experience which didn’t help anyone but was/is extremely uncomfortable. And going further back you get stuff like transition being denied because a psychologist doesn’t think you’ll be attractive enough.
