Is acceptance inversely proportional to offence

I would say not there are lots of things that I might not find acceptable that don't come anywhere near offending me.

Most of the time. On a rare occasion you will say "They offended me but I still think they're cool."

Generally.

Most times yes.

Loosely. The don't give a fuck zone between them provides some variability. Some things that aren't accepted land in there but don't quite reach offense. And vice versa.
