People have a style of "arguing on the internet" that is just really really dumb. You can keep the argument going forever with purely airhead responses.
1. You ask the other person "Are you saying [insert dumbness]?
2. You present imaginary facts as "arguments". Future facts are all very plainly imaginary. Go through an internet argument and look at all the future facts. It's pathetic. A second category of imaginary facts is "most people do [whatever]" and "most people don't do [whatever]
3. It's popular to call somebody else a hypocrite, AS IF somehow that meant they were incorrect. That's incredibly stupid. When hypocrites talk, you better listen to what they say and think. They typically tell the truth. Maybe somebody you'll meet DOES the truth but tells lies, but it's pretty unusual.
