Pacopoolio: I don't think whether you get a date or not on a dating site is a fair measure of whether you are disadvantaged or discriminated against. If people are not attracted to you for whetever reason then they are not attracted to you. Unlucky!
That would seem to have more to do with how many people use such sites as part of their culture. I have no idea how match.com or other online dating sites are viewed within black communities.
If you followed your claim to it's logical conclusion then if someone was "fair" in your eyes they would like all people of a race equally which is never going to be the case.
I general I don't find black women as attractive as white women. But I find some black women very attractive and some white women a lot more attractive than others. How is race playing a part in that? If I'm discriminating against anyone it's simply people I happen to find less attractive.
Other things such as shades of makup come down to market forces in the same way that people with big feet have less choice when it comes to shoes - stores stock more of what they sell. I'm sure there are stores that do very well targeting a different demographic. If there was demand for product and money to be made I don't think stores would *not* stock things because of some corporate-level racism.
