I am autistic and was once dogpiled on HexBear, but in my particular case I don't complain, because what I wrote was indeed bad and I later apologized.
I not only adjusted my ideas, but I learned that one must avoid even the appearance of being a chud. Hypothetical example: suppose someone experiences a particular case of black-on-white injustice (it might happen, even if very rare). If then they get emotional and write a screed about "reverse racism", they might technically not be completely wrong, but every leftist will take them for a white supremacist, even if they were just naive and tone deaf.
