Ah, they're just saying you're racist cause you're carding them & rightfully holding them accountable for suspicious behavior, you know that but I'm sure it still gets on your nerves, as it would anybody's.
Sadly, this kind of bullshit can often make people BECOME racist, based on the actions of a few thug idiots.
Be careful Girl! Shootings, obnoxious customers...
I haven't been subject to that much reverse racism b/c a lot of people think I look Hispanic. But it's a tool people seem to use when they don't have anything else rational to say, or when they're hiding something. Sounds like you have them figured out.
