I feel as though it is up to each of us individually to decide where to draw the line. So long as the line doesn't cross into drinking alcohol, of any content, then we get a passing grade. I sometimes order virgin margaritas but have decided not to drink NA beer, probably because beer was my drink of choice, but I freely admit that it's a position that is a bit difficult to reconcile. I think as long as we are thoughtful about what we are doing and why, we are probably pretty safe.
