I'm not sure if you're applying that statement in mass or not, but I have seen this reasoning from both sides, straw-manning people into a belief system and calling them irrational because they disagree. I see this much more about the right from the left though.

I think if you sat down with an educated conservative and an open mind you'd have a different point of view.

If your statement was just a blanket statement about people in general, I apologize for mis-categorizing it.
