The ideology is some grotesque, clownish monster that doesn't seem to really care about anyone except to expand rights that mostly benefit males at the expense of females, and to make people play along to others' sexual fantasies. That's certainly reductive, but it's a little hard to see beyond that sort of stuff sometimes. But I think your last line could be helpful a mantra for changing minds that have fallen victim to TRA and this ideology. That sort of encapsulates things.

The morbid irony is that it's dehumanized everyone, really. It encourages ignoring others' suffering, save for language policing, even trans people because no one is going to acknowledge serious issues that would be healthy to address. The ideology may have started from good intentions, but it's turned out to be heartless.

TRA seem drunk on power, so maybe rights eroding to a point that it affects more and more of those people to where they stop and challenge things seems like might be something that could change that.
