Myths, for some reason, often have loopholes. Achilles is invincible, except for his heel. Samaritans are bad, except for some good ones. So sometimes you can position yourself as matching the loophole and get a pass. Sometimes this is humiliating, though, or funnels groups of people into acting out narrow stereotypes.
That lesson took me embarrassingly long to learn, but it's a good one.
I haven't given much thought to pattern-matching a loophole as a strategy, but your observation is key: people are willing to make exceptions, you just have to figure out how to get them to make an exception for you.
How to do that? Virtue signal. Watch other people for ideas. You won't have to watch long, people love to virtue signal and do it all the time. Validate their VS to score some quick points, swallow the small amount of bile that it brings to the back of your throat, and then pick something politically adjacent but not so directly similar as to compete/threaten. Those constraints are pretty loose, they should leave you with a wide field of possibilities to choose from. Pick the least unpalatable and you're set.
Leave home.
edit - that was maybe slightly personal as responses go, but I think in a situation where you find yourself to be a pawn in someone else's psycosis, then you should extracate yourself from it and try and help at arms length unless you have a will of iron.
Most people believe that they, and they alone are the guardians of universal truth. Ries and Trout really hit the nail on the head when they discuss the folly of trying to change a mind.
“You want to change something in a computer? Just type over or delete the existing material. You want to change something in a mind? Forget it.” ―Ries and Trout, The 22 Immutable Laws of Marketing
“The mind, as a defense against the volume of today’s communications, screens and rejects much of the information offered it. In general, the mind accepts only that which matches prior knowledge or experience.” ―Ries and Trout, Positioning: The Battle for Your Mind
On the other hand, due to various forms of prejudice, certain characteristics (race, gender, accent, and what not) increase your chance of victimization. This while sad, becomes fuel to people who dedicate their lives to fight for injustices.
I feel like the author of the piece might even advocate going along with-- or at least not wasting your energies fighting-- many cases of socially useful fiction. But that hardly works when you happen to be the person or of the creed one targets.
