That was a World War II joke

Ignorance is bliss.
I'm not following world events at the moment.

You mean like Germany and Russia?

Truce.

Then we put both things behind us and we both grow up

Either works.

Or perhaps you could ignore me

Still offensive.
Then ignore me, very simple.

I didn't use it as a punishment, more so as a punchline. I could've easily said "your hat sucks" and kicked you. There is no "fairness" when you've been being as intolerable as you have been for past, well, forever.

In all fairness, that comment is very offensive. You using it as a sort of punishment makes it no better.
