Stop making other people's character flaws your problem. As long as someone doesn't hold a position of power, or has any ability to actively influence the lives of other people, who cares if they're racist?

That card has been thrown around soo much lately, it's actually diluting the issue instead of improving it.

It's just someone getting offended by the comments of complete strangers on the internet. Unfortunately that's your problem, not the stranger's. Guaranteed they won't care about your feelings, and your not going to change them. You can however change how you react to them.

That's just my two cents, and I'm a nobody so if this comment offends you than that just says a lot about your mental state. Who gives a shit about the opinion of a nobody? An emotionally unbalanced or insecure person might.
