This argument makes no sense. I based my words on your statement not your person and it wasn't even addressed to you. I picked up your argument and from personal experience explained why those people that you described see it like that. Making a very wobbly assumption based on criteria that puts one in a protected group is profiling and it gets old when you keep hearing it again and again. Moreover the same reasoning can lead to far more offensive conclusions then calling someone a rapper.
I never mentioned your race and it would make no difference to the argument: a black person in Africa will have just as little experience being profiled as a white person in the US. My "prejudice" wasn't towards you but towards the people who think making such assumptions is normal. Pulling this absurd "you racially profiled me based on my opinion" card now suggests to me that minority or not perhaps you also do not understand the real issue.
I would have thought that people who suffered this kind of profiling understand why it's a problem and actively steer away from doing it or even condoning it without the need for further explanation. And I get it that some are doing it without realizing it's a problem. I'm not assuming bad faith, just lack of understanding.
I'm not taking issue with you doing that, I was just aiming to illustrate the fact that everyone does this constantly. It's easier than thinking - it saves energy, we evolved to do it. It'll be hard to get rid of this and therefore maybe shouldn't be in the focus as much as it is.
