I don’t think we should treat human interactions like a technical problem, where we look for edge cases and outlandish hypotheticals to probe the edges of what is possible. If “thank you” became widely associated with bigots, and had some negative meaning, to the point where it genuinely distressed people, I’d avoid it. I think it has a widespread enough normal meaning that there’s almost no chance of that happening, but it isn’t impossible.
