When there's not, I have developed a strong skill in suckering such blithering idiots into cul de sacs of their own ignorant reasoning, until they are reduced to mumbling to themselves. But, why should I ever have had to DEVELOP that skill?
Because you are a strong person that recognized that overcoming adversity is part of being successful, and developed a strategy to do so.
We are all born the same way, and discover our gender as we grow up...but, due to family influences (e.g., drunken men abusing their wives, "men of the house" who want their women "barefoot and pregnant"), some males grow up with a tacit belief that women are, somehow, inferior to men.
No, we are not all born the same way or into the same circumstances. We are born into a huge variety of different environments and with a complete genetic toss of the dice. You play the cards you're dealt, and hopefully try to do the best you can. Or you can just fold. Expecting everyone to be dealt the same cards is just unrealistic. In general, the more a person has worked to overcome adversity or "injustice", the more I tend to respect them. It's the ones that cry "waahhh, the world is not fair!" that I look upon with disdain.
There's a name for these people: They are BIGOTS (and it often extends to other differences, like cultural heritage, skin color, education, that are patently irrelevant to judging whether the person is "human" or not).
All people are bigots. We're all guilty of bigotry and prejudice at some point, some more so than others perhaps. Trying to eliminate it is an exercise in futility. Recognize it and deal with it (which to your credit, it sounds like you have), but get down off your high horse if you think that you have never been intolerant towards others who have had a different opinion than yourself. I am not saying "yay, bigotry!"; I am saying that it's just a part of life.
Fortunately, not all men are chained to this philosphers' wall, drawing conclusions from shadows and accepting them as fact. There are many men who exhibit humanity and treat ALL others with respect and dignity...and they are a delight to work alongside. Unfortunately, they are outnumbered by the dolts, in my experience.
Welcome to planet Earth. Someday we'll all live in a Utopian society where we'll all be drinking that free bubbalub and eating that rainbow stew. Cherish the good people, and try to work around the bad ones.
