Some absolutely are. There have been massive discussions about Stonewall on vet groups on Facebook (pro-trans, I believe) and Vet Surgeon forum (more mixed - think there’s a preponderance of older vets there) where there were absolutely some ideologues. The RCVS was also heavily captured, Stonewalled to the hilt, with a social media policy that used to really worry me.
I think lots of vets are from the same privileged background as other groups whose children become social warriors at their naice school.
I think, unless she has some actual evidence, that she’s quite likely on a hiding to nothing. The timing of her “sacking” could be significant, I guess, if it happened at the same time she hit the news. She might also have some evidence of the dispute with the vet who’s no longer there, but if the clinic staff are united against her and willing to testify that she’s been rude, it might be her word against theirs.
It will be interesting to see how it unfolds.
