While it's good to be open minded to some alternative views, maybe it's just as simple as someone might not fully grasp the theory to begin with. How to ''accept'' something of which we have no understanding, or full understanding. I was talking with someone about a variety of theories the other day, and she didn't understand a one of them, which is fine, but she didn't WANT to understand them. lol So, she dismissed them as having no validity. So, it could be as simple as that--dismiss something of which you don't understand nor want to understand. haha
