What is the opinion on Elizabeth Warren's actions and how they were perceived by different groups of people?
Warren broke the rules, she knew what she was doing, and acted incredibly divisively, but of course it is courageous when it is a Democrat or "minority", but rage inducing racist/bigotry/homophobia/islamaphobia when done by anyone not of these groups. 
Warren is not a "courageous hero", she is a class A political hypocrite, and I should hope all others who attempt to pull a similar stunt are stopped.
