As far as I can tell, the most unifying characteristic is a willingness to bully in all its forms. It's the liberal hive-mind. Every drone partakes of, expresses, and acts upon its all-pervasive omnipotence.
Last week a very longtime friend shocked the hell out of me when he told me that Hillary should be forgiven for breaking any law that she could if it meant keeping Trump from being elected.
I still consider him a friend but I am very, very disappointed in him.
