Another is inappropriate use of double quotes to imply that your intended meaning is different from commonly accepted one or one which your opponents will use. You know I am "right", ain't I?
A "light up" or "take it easy" can often be used to disparage serious discussion on a topic by terming opponent snobbish or uptight without noticing the logic of argument. Don't find my jokes on poor kids funny? Lighten up!
And one more is to bring Hitler into picture somehow or other. By the way, did you know "Godwin's law" regarding long drawn arguments?
As...discussion grows longer, the probability of a comparison involving Nazis or Hitler approaches one.PS: I am back!
