Are whites racially oppressed?

While that would be an ideal society, it's not possible. Most opportunities given to people in this country are privately offered, such as businesses giving grants for research or scholarships for universities. It's never really going to happen as long as any business can be privately owned and not run by the government and well... since our country was originally designed to have limited government control over the people, it's not going to happen.

If private businesses want to be racists/sexists, I guess that is their choice (although in this day and age, that means taking a risk of backlash from the community).
Although, this is no excuse when it comes to laws in this country.
