A polite bigot is a bigot nonetheless. A true warrior knows that courteous words do not dilute the poison, but only serve to conceal it until it has spread. Civility in the service of hate deserves no polite response.
Hence my uniform contempt for all Republicans. 3-5 pose as civil assholes, but they are assholes nonetheless.
In my opinion, the #RepublicanParty during 2005-2015 were more or less "civility in the service of hate."
Since 2015, a significant minority of Republicans have become uncivil advocates of hate and bigotry and they are dragging more into the pigsty with them each day.
