What to Ask anyone who was spouting Leftist platitudes

Many years ago I ran across a list of questions to ask anyone who was spouting  Leftist platitudes

[1] What do you mean by that? Find out if they understand the meaning of the catch-phrase they're throwing around. Many casual leftists don't comprehend what they are actually pulling for. If they can't describe IN DIFFERENT WORDS what it means, they're ripe for getting educated.

[2] Where did you get your information? Force them to give up their source(s). Now you can attack the sources.

[3] How do you know you are right? Let them go on an on and on...

[4] What happens if you're wrong? This forces them to examine their positions and defend them. This is where they will deflect and deflect and deflect. Don't let them off the hook!
