I don't think that's necessarily true. Some of the students of today are the faculty of tomorrow; in my experience the students that eventually become profs are not representative of the student body as a whole.

For example, much of the funding available in US physics is DoD funding. Many students (and grads / postdocs) have ethical issues with working on DoD projects. However, refusing DoD funding is not a good move for early-career researchers. So in my experience successful new profs tend to be more "hawkish" than grad students in general.
