MAP

What's a good way to ask someone on a social media app if they're a MAP without other people figuring it out? I saw an elderly man going off about how unfairly people were treating a minor online and how he wanted that young boy to know he had allies. It was a very impassioned speech and gave me big MAP vibes, but I couldn't figure out how to ask "Are you a MAP?" in a way that wouldn't get me harassed and likely even banned. It's pitiful that the only way we can publicly talk about MAPs is with hatred and bigotry and that we need to use roundabout ways of identifying each other, but that's how things are right now. How would/do you go about it?
