Isn't being TOO open minded a bad thing for us?

It seems to me that liberals are TOO open minded, and Yes, me the conservative is somewhat closed minded, But that for a good reason, its not because I want to oppress others, it has to do with self respect, self dignity, and self control. So to me, one that is TOO open minded in those (self's) that I listed, is not anything but self righteousness.
