First, it seems that minorities tend to commit more crime. Not enough white criminals go to jail and black men may very well get longer sentences. I'll grant that.
Don't know about real estate. As for lending practices, as far as I know pretty much everyone is looked at as part of their demographic group. I'd assume a black owned business has a higher failure rate, thus blacks will pay higher rates.
Banks are in business to make money. Smokers pay higher insurance rates even though not all cost more than average. Teen males pay higher car insurance. That is less racism than business.
Women make less, in general, than men because women do not spend as many years in the workplace. For the same work, same education, same experience, pay is the same.
What does "white-male dominated society" mean exactly? How are "they" oppressing me? I honestly cannot say I have ever been treated badly for being female. I've been unable to do certain jobs (more dangerous), and I was glad. LOL!
The only time I felt I was treated with less dignity than I deserved was when I was on WIC. Those people assumed that because I was a relatively young, low income military wife, that I was completely brainless. I shrugged it off. Some people are ignorant and I have no time for them.
