Straw man argumentation -- the process of taking an argument of the opponent, distorting it or taking it out of context so that it basically changes meaning, and then ridiculing it in order to make the opponent look bad.
Citing inexistent sources --There's a very common bad habit among the majority of people: They believe that credible sources have said/written whatever someone claims they have said or written.
