Vegetarians may wish to be careful with beer. Some vegetarians aren't ideological/religious about it, and some that are draw lines in different places.
Quite right, people are vegetarian for a variety of reasons, and draw the line in different place!
It's worth noting that good results can be achieved with proper temperature control and irish moss, isinglass is not always needed. Also many/most keg beers are filtered rather than fined.
That's really weird. At that point who are you trying to convince that you're a vegetarian? These are people who apparently aren't even trying to be vegetarian. I can understand people who'd claim to have a preference to not eating meat, but two-thirds in the last day is ridicules.
I where a vegetarian for 12 year, without having any real reason, other than I felt like it. Even at my most drunk I could always remember that I didn't eat meat.
Two-thirds... damn that's stupid. "I really want to be a vegetarian, because fluffy cows, but OMG cheese burger". Some people are weird.
