Beware the political "label"

I have a question for y'all.

Is a person's beliefs about the world and what's going on in it a reflection of their political "ideology" or, is that person's political affiliation a reflection of their beliefs?

The guest on Paula Zahn tonight (Friday) talking about the political affiliation of college professors was pressing on the idea that these professors are pushing a political agenda rather than simply expressing their own personal beliefs.

I found this little exchange a little scary. I'm not too keen on my advocacy of human rights, fairness, justice, and sane/humane policies painted as a political agenda.
