So you're using a definition of Progressive written and perfected by people who self-identify has hating so called progressives?  How is that supposed to bring you closer to an understanding of our perspective?  All it does is drive a wedge between you and the people you are talking to.  Just from what I can see in the link text without clicking on the article, I can see that the author has absolutely no idea what he is talking about.  Institutionalized racism?  Totally against what progressives stand for.

If you want to understand something, don't come at it from the perspective of someone against that something.  It really doesn't help.
