@francesh2227 @KweenInYeIIow @GlennKesslerWP In formal logic, that's called the "ad hominem fallacy." I know in online fights that term has come to mean "saying mean or insulting things about people," but the real definition is trying to discredit an argument or evidence based on the attributes of the person offering it. — PolitiTweet.org
