is anyone else low masking but high IQ?

I keep seeing people online say that if you didn't get a diagnosis as a child, you're probably just high masking. But I'm actually very low masking and was demonised for it a lot - I have a high IQ and I wonder how much of the child tests are just fucking IQ questions (as well as being cryptic as fuck, if I knew I was low masking and not just a Bad Person For Mysterious Reasons, and therefore everyone does X thing sometimes, I would have answered he questions differently! But no, she just refused to explain!).

It feels like people expect my intelligence to erase my autism and therefore I am Bad Person in their eyes for that being bollocks. Or, I am Stupid Bitch in their eyes and convincing them that I am intelligent and don't deserve ableist abuse is impossible. Some people seem to want to believe both at once, I do not understand normals.
