As a law student that has debated cases of affirmative action, aka positive discrimination, I can tell you that in most cases (not all) I don't support it and it goes against any secular, democratic constitution. The problem is positive discrimination WILL negatively discriminate someone negatively as a side effect (for instance, a minimum of black people for a university regardless of skills will leave white people with more skills out, so they will be discriminated negatively). Equality means treating alike what is alike and differently what is different. I do agree that social minorities should be supported and given good conditions to live and put their kids in school, these kids should have extra school support themselves, etc. However from the moment you get a job, into college, etc, just because of your race, gender or religion that's when I start being against it. If my constitution states 'None shall be discriminated by reasons such as race, religion or gender' that goes both ways in my interpretation analysis, you can't benefit or prejudice someone, simply treat them alike.
Whoever fights monsters should see to it that in the process he does not become a monster. And if you gaze long enough into an abyss, the abyss will gaze back into you
