As far as I understand the term, white privilege means some kind of economical and political advantage of whites over other races. Meaning that the outcomes are different, depending on one's race. From a brief glimpse of the paper, it is quite clear that the authors push for equality of outcome and label their position as 'liberal'. However, many people disagree. The classical liberal position is granting every person equality of opportunity, saying nothing about equality of outcome. And for a good reason: you actually can't have both. Either everyone is equal at the start of the game and then the more successful achieve more, or everyone is equal at the end, and for that you have to make their opportunities unequal.

When you think about it this way, equality of outcome is essentially a Marxist rhetoric. So it's quite understandable why many people don't like politicians who advocate this controversial position.

If, the other hand, what politicians really want is a greater equality of opportunity, they really should make that clear. But I don't think they usually mean that, given that people who talk about white privilege are usually the ones who push for so-called 'affirmative action', which clearly reduces equality of opportunity in favor of equality of outcome.
