You don't believe that any of what I said is true because you know for a fact that American universities have no systematic liberal bias? "No way"? No possibility they do?

Okay, then, your credibility can be judged by other readers on that basis: no way there's any systematic liberal bias at a place like Stanford.

I claim that these universities are powerful, overwhelmingly liberal-leaning, highly-politicized internally, highly-influential externally, and that their internal politics heavily impacts the nature of their significant external political influence. The corporate comptroller at Harvard does not have to write a check to an individual politician for Harvard to exert its political influence. Harvard has plenty of ways to influence people that don't require paying for political ads. The politician may even be writing checks to Harvard, hoping to get his son admitted.

And readers can judge the credibility of that claim, too.
