Tracing the trend of active discrimination against white people to the Civil Rights Act seems like a huge stretch to me. The supreme court has had to tie itself in knots to explain why affirmative action *doesn't* violate the CRA (it does).
Notice who's using Title VII here and who's trying to avoid it, though. Grutter wouldn't have gotten to the Supreme Court without the CRA because there would be no federal cause of action. That courts don't interpret the CRA to prevent this doesn't mean it encourages it.
