Fetishising trans people is bad. But if you’re trying to say people are wrong for having gender transformation based fetishes, you’ve completely lost the line here. It’s a complex topic, but you’re denying people’s sexual expression by saying it’s “not ok” to fetishize anything about gender. Which is just an absurd take. Someone can be trans and be sexually aroused by the idea of having sex and/or masturbating as a female. Or they might not be trans but still have that sexual fantasy. That’s totally normal and isn’t “fetishizing trans people”
