This is where you miss the whole point! You just don't get it.
History isn't a Republican thing or a Democrat thing. This is what I am talking about when I said you try to fit ideas into your narrow prejudiced framework.
History is all about what happened, why it happened, and what the ramifications of the events are. As such, ideological viewpoints color the relative importance that gets assigned to various bits of data, and more so to the various interpretations of why events happened the way they did.
History and ideology are intertwined, however much you may deny it. A large portion of historical revisionist scholarship involves reinterpreting the historical data from a different ideological perspective.
To a large extent, the dominant ideological perspective among campus social science academics is Democrat. Even that radical right-wing NY Times has to admit it. That lopsidedness cannot fail to color the academic discourse, particularly given the tendency of some on the left to refuse to grant any legitimacy to viewpoints from the other side.
