Catchphrases that haven't yet caught on

I interpreted the equals sign as saying that the two were equivalent; shouldn't it have been an arrow if it was an "If, then" statement?

I dunno. I never took any formal logic courses. I'll have to defer to you on this one.

Touché. I should have used -> to state my intent. However, my point is technically correct (I think.) We were taught that A->B is equal to !B->!A, but in everyday language this isn't always true.

My point really was that everyone else is likely to include dodging much more than pg is. Wouldn't you agree?
