Some are a little too OCD and literal and too focused on name calling, staying on topic, defining terms, complaining, anything but talking about the gist of the subject matter.
Someone says "no one thinks there should be no government" and someone else responds "I know one person who thinks that and you said no one thinks that...gotcha"
Instead of addressing the point which is (most) everyone agrees that we need some government and the question is how much?
Two reasonable people can disagree on the level of government needed but it's hard to find two reasonable people here.
One will say "you're not literate, you're an idiot, you said it's hot in Phoenix but you didn't cite a study..."
Those are all tactics when someone wants to win a debate and doesn't want have a discussion.
It is interesting that Bitcoin has doubled in price since we had that particular discussion though...
