While I don't see it as meaning to be racist comment (I first took it as, "You'd only drink it at gun point") I can very easily see it as being perceived as racist. An apology would go a long way, me thinks.

Of course that would mean much less wank and the always amusing race=religion=country of origin confusion. I think anyone that uses a variation of "OMG! You are racists against Muslims" should automatically lose the argument. It is impossible to be racists against Muslims.
