My deep-seated social ignorance and blindness? I don't think so. I am very well aware of the difference between real racism and personal accountability, and I took the time to point out before I even made a statement regarding personal accountability the importance of consistently applying the rules in one's own establishment. I've also managed thousands of people in my career, and my statements regarding consistently applying rules don't just come from some highfalutin book I read, but from experience. That Starbucks manager shot themselves in the foot by failing to consistently enforce the rules, and they are part responsible for this escalation.
The other part is this though. I'm sorry you can't comprehend what I stated when you attempted to paint me as some racist bigot, however at the end of the day, these two boys weren't paying customers. And when asked by management to leave because they were taking up seats reserved for paying customers, they refused and chose to escalate. When asked by the cops to leave (which, it's sad it even got to that point), they refused and chose to escalate. Does driving over the speed limit because "everyone else is doing it" make it okay?
It's called personal fucking accountability, and it seems to be lacking these days in an age where we can just cry for attention on social media. If I were one of those boys and a manager asked me to leave because I hadn't bought anything yet, you know what I had done? I'd have left! Why? Because I'm a mature enough individual and I can recognize when I, personally, am in violation of an establishment's rules. I don't care what other people are doing. I care about what I'm doing. I was also taught respect and honor growing up, and I personally recognize what privileges are earned when you're a paying customer and when you're not.
Also, I grew up in the south. I know what real racism is, and like you pointed out, it's disgusting. However, this is not it.
