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.

Vegans, on the other hand, draw a very simple line, with very simple (and powerful) rationale.

Yes, Vegans have the moral highground and none of their dietary choices are detrimental to cute little animals.

Well, maybe simple, but their rationale is nowhere near powerful in a lot of people's minds.

> Another survey from the USDA, also conducted by phone, put the [proportion] of vegetarians who’ve eaten meat in the last day at about two-thirds.

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.
