This is the problem with ... I don't even have a name, let's call it "Lazy Political Correctness".
Intelligent people try to spread an idea, like, lets say, the fact that race does not make a person superior. So the idea spreads that we should not judge a person by his or her race, because it doesn't determine their personality or integrity.
Then we expand on that: ethnicity, gender, sexual orentation, these things do not make a person better or worse, smarter or dumber, more or less honest or competant.
But then the catch phrases start, like "Don't judge people." And lazy people who follow catch phrases without thinking of the logic behind them don't know how to apply that.
The idea is not to judge people based upon aspects that do not shape a person. People should be judged not by their race, ethnicity, orientation, or gender, but by their opinions and their actions. It's wrong to say "I don't like black people" It's okay to say "I hate Adolf Hitler." Or "Ann Coulter is a cunt!"
One should use judgement, good judgement, everyday. Use good judgement when it comes to making friends, doing business, and crossing the street. And, Mizz. O. I think you should consider use better judgement when it comes to taking up causes.
