I just saw a cartoon that may apply.

Figure 1 voice: Are you coming to bed?

Figure 2 Seated at computer: Not right now.

Figure 1 Voice: Why not?

Figure 2 seated at computer: Someone is wrong on the internet.

Yep.

1. My wife would relate to that cartoon, kairos

I usually see her off to bed and then resume the epic online debate. But sometimes I'm on such a roll typing away that I'm delayed.

Problem is, I can't recall many instances of changing any minds on the other end of the argument. It's largely an exercise in futility. I get drawn in less and less, but still can't help myself sometimes.

2. The interwebs are full of stupid

And we know how successful it is to fix stupid.
