While I get the rest of it, I don't follow on using immutability as the test of what you are non-judgmental towards. People can have immutable qualities that are completely incompatible with any form of social contract. I'm thinking violent behavior attributed to various mental disorders. Disorder being applied not as a judgment, but simply to indicate it doesn't allow them to have what they consider a fulfilling life, what with the rest of us commiting them involuntarily. There may or may not be medications or treatments that might modify those situations. If there are, then we are asking them to modify their natural state to be accepted. I think in that specific case and perhaps others it is reasonable of me to demand that of my in-group. I don't want to get stabbed because they were instructed by a command delusion. I know the medicine and treatments are not ideal. And if they fail to comply with treatment, or it doesn't work, I reserve the right to judge them for their nature.

The parallels for orientation are clearly there, and given enough clockwork orange type abuse, I'm sure you could make me attracted or repelled by just about anything, but I don't choose to judge people with sexual orientations that differ from mine, not because it is their immutable state, but because there are no valid arguments for it harming me or society at large. Population seems to be managing itself. If it was runaway, I might judge people who engaged in behavior that might add to the population, and if there was barely a breeding population of us left, I might judge those who didn't.
