"Positive discrimination"
is racism. Or sexism. Or whatever group-ism it is being used to disadvantage at the favour of some other group.
The idea that whites are privileged is the opposite of reality in many cases now. Non-whites have "entitlements" which whites do not, which favour them in things like hiring.
The concept itself, that someone of a certain skin color should be given preference over somebody of another skin color, is racist whatever way you wish to spin it. If you're favoring one group because you dislike the other group, you're the kind of shitty person you mentioned.
If you're favoring them because you pity them, and that pity is derived from your subconscious association with a group that you think aught to be pitied because of a certain stereotype (eg, skin color), then you might think that you're a good person for having such feelings - but you're really just a closet racist.
I get that it has not always been the case that everyone had equality of opportunity, and that certain groups were disadvantaged in the past. We can't change the past, but we can create the future. Instead of repeating the past, by reversing the group roles, I'm in favour of eliminating all forms of discrimination.
I'm astounded by your lack of self-awareness of your racism and sexism. Apparently all white men are privileged, or at least, some of them are, so we can use this to make judgements about all white men. Great. You're not a hypocrite in the slightest.
