Wow. This discussion has certainly taken an interesting turn. Just so I can be sure I understand it, if there's this conversation:
Bill: Hey Ted, we're having a great game of D&D and we have an opening. Are you interested in playing? Oh, by the way, we have a couple folks in it who have a beer while we're playing every so often.
Ted: Sorry, Bill. I make it a point of not gaming where there might be alcohol involved.
In this case Ted has somehow offended Bill?
Case two:
Bill: Okay, so the ogre rears back and clobbers Socrates with his greatclub...that's 17 damage.
Socrates: Well I'm out...hmmn, Methinks I think I will fetch a glass of wine, since Ted's character is out of healing and I've already spent my second wind...
Ted: Umm, didn't we agree to no drinking during the game?
Socrates: certainly as a general principle, but I shall only have a small glass, and everyone knows I am renowned for my ability to drink and not have it affect me.
Ted: Uh, I'm not comfortable with that, I should probably call it an early night.
...once again, has Ted done something offensive?
If you believe Ted has been offensive, replace drinking with smoking, watching the TV or simply something that you (the person reading this) don't like. If your opinion changes,is there a difference here, or is it just a preference that you don't share?
Personally I think we should give personal preference, for whatever the reason, the prerogative to opt out, and not have anyone be insulted by it. If I'm totally off base here, I'd like to know why that is...
