"So when ONLY the conservative viewpoint was taught, it idicated [sic] that the liberal view had problems with truthfulness?"

I wasn't talking about teaching. The "student activists" are writing their own scripts.
Expressed, and unfortunately the lies get out there too. And I very distinctly typed "truthiness", because Jon Stewart.

You have to listen to both sides, at least until you're sure one side is significantly full of shit, then make up your own mind. I sometimes see Fox, because it's on at the gym...until I start swearing and saying "that's NOT F*ING TRUE!" and people on the other bikes look at me funny, and the TV is way too far away to hit with my water bottle, anyway, plus they'd kick me out.
But consider the liberal idea "the President lies".
...and the conservative answer: "he does sometimes, but he's still our guy, so we give him a pass.
Liberal idea: Unrestricted access to military-style weapons isn't a good thing"
Conservative: So what?! Don't mess with my guns!
or, more realistically:
I agree with you, but the NRA doesn't, and they own my candidate.

It's not actually a partisan issue.
If you believe trying to stop gun violence IS, you're somewhat of an outlier.
