That's the irony of deep thinking liberals...they can be trained to think they're smart when they don't have a clue...then they have to group think to maintain any sense of self-esteem...
Even when they see the truth...they cant admit it because their self-esteem is threatened...and their self esteem is more important to them then any truth...Liberalism is a convenient excuse for personal insecurity.....hence the term....."useful Idiot"
In the religious context, their self-righteousness is more important to them than the truth.
This is why, when you discuss an issue with a lib, you think you're discussing the issue, and they act like you're attacking their "goodpersonhood".
