If a friend or relative makes a racist or homophobic remark, do you tend to confront them or let it slide? Are you more likely to confront them if it offends you directly or someone else who seems reluctant to speak up?
Most of the time, yes, I try. Every single time?
No. And I'm deeply ashamed of that. I don't even confront them when they're aimed at me and mine all the time.
Sometimes it's because of the person. When my Alzheimers afflicted 90 year old grandmother let's the foolish fall out of her mouth - well there's no profit to correct her. Ok she's an extreme case but there are others as well who you just know are going to be a waste of time.
But usually it's because I'm tired and I just don't want to do it AGAIN with someone who, I can almost guarantee, will learn nothing from it other than "Sparky's an oversensitive PC type." And it's so damn common that I sometimes feel I'm having the same argument 3 or 4 times a day
