I believe that if people are questioning the safety of puberty blocking medications that have been used since the 80's, it isn't a valid medical opinion motivating the questioning. In that case, there is no stretch to classify it at least as Transphobic. I've heard lots of references to TERF Island, but that's more about the feminists seen as attacking Transgender individuals. I think that Transphobia in particular and anti-LGBTQ+ hate in general are being ramped up globally as it's a way for authoritarian-minded people to focus hate on a minority to distract the populace from other harms being done, and that doesn't look like it's going to change any time soon.
If I believed that there isn't a possibility of a successful attempt to get out of it, the fact that there is a judgement would reassure me. As I don't have that confidence, I am not reassured.
*fingers crossed*
I want an acceptable 80's level Acronym for LGBT that makes them as terrifying as COBRA!
