I know, Dale. I know what are talking about, and how do you feel (and many others).
Yes, biased views and prejudiced language do save a lot of time, for many. As for me, saving time is not an issue, I try to see everything around in a unbiased way, destituted of my own predispositions (at least, I try, don´t know if I succeed).
Imagine, when I went to Rio and lived there for a while, I collected the magazine "Eletrônica Total", let´s say the cover price was 7 Cruzeiros at the time. As soon as I asked the price, the guys at the newstands would prick their ears at once. And, as on cue of my accent (northeastern one) they would say that it costed 9 or even 14 Cruzeiros, the end result? I never would come back to such newstands. Tough, I never would argue or make a scene on spot; I simply would nod and never would come back.
Problem is, as if prejudice wasn´t such a bad trait, it came along with actions that would hurt in the pocket.
Even at the Uni. I have had ‘peer teasing’; but I took it lightly, even mocked of myself and at the end of each term they turned into real friends of mine.
