Maybe I'm just not smart/eloquent enough to come up with a response like GP, but often I'll have arguments in my head where it looks like:

- make a point A

- oh, counterexample with point B

- ehh that's a good point logically...

but I'll just go with point A anyways, especially when point A is something generally optimistic, and point B is cynical.

I don't like going into social arguments for this reason - it's very easy (and often logically correct) to create an ad-absurdum counter-argument to a lot of our general social beliefs.

But to be a functioning human being, sometimes you just have to take the optimistic choice regardless. I know that certainly when I was constantly listening to B, I was depressed out of my mind; would rather be "delusional and stubborn" on some things than depressed.

Twice two might not be five, but it keeps your sanity.
