So ... you don't have any rational argument to justify your position, then? I can sum up mine in a paragraph or two. You should be able to do your elevator pitch too if you think it's important - preferably using ordinary words instead of jargon from sociology textbooks.
And your point is? Again, you seem to be implying that "career" is the be-all and end-all of existence. As one wag once remarked, nobody ever says on their deathbed: "I wish I'd spent more time at work". You appear not to have thought through the philosophical implications of your position.
Most women eventually end up as moms, because they want to. Most men end up as fathers, because they want to. Unless you're a fan of the Human Extinction Project, that's probably just as well. True enough, some fathers bugger off after their biological role is done. Still, 60%+ stick around to see their kids grow up (at least, as far as Society allows them to). Why do you reckon that is?
OK, you're young, so you don't have the grim reaper drumming his fingers on the armchair next to you saying: so, are you done yet? You probably think you'll live forever, and perchance change the world while you're doing it. Some things about the world just don't need changing, is all. As someone else remarked, you're tilting at windmills.
Here's another of my favourite sayings: youth is wasted on the young. You have all that energy and drive, and you choose to fritter it away on things that simply don't matter.
It's a bit more complicated than that. There is some actual research on the subject, which I hope you'll agree trumps PC speculation. It works something like this:
1) The hiring manager hires people he likes. He decides whether he likes people in the first 30-60 seconds of the interview. If he's an out-and-out racist, he will dislike people who don't have the same skin colour as him. However, such people rarely make it to management positions because they tend to make poor judgements in general terms.
2) In cases where there is a prolonged acquaintance - say, an internal promotion - whatever prejudices the manager holds towards the candidate's group (black people, white people, gays, whatever) will have been modulated by his experience of that particular individual. In other words, he will make the judgement solely or mostly on merit.
Funnily enough, personal relationships work in much the same way.
I'd also say that if someone promoted me simply because my skin colour makes me a 'disadvantaged minority' - which technically it does - I'd be deeply offended. I don't ever want favours from the privileged (whoever they are) because they think my "race" requires a leg-up, nor do I want slow-witted college students fighting for the "rights" that they imagine I do not have.
