...But, you might be right about the father being a racist...
I agree. I think I used the term too loosely. The kid's father, by his actions, comes across more like an opportunist or whining idiot than a racist, per se.
"Playing the race card" can, I suppose, be done by someone who is not necessarily a racist, but using race as a weapon puts a person damn close, in my opinion. Here, I confess to some emotionalism which affected the tenor of my response, but it is, after all, a response to some spectacularly thin "reasoning".
