I debated whether or not to respond since you just sound like flame bait, but I guess I'll respond...
Vegan/vegetarian is a description of a diet, _NOT_ a philosophy. People can go vegan or vegetarian for a number of reasons:
1. boycott poor treatment of animals in the livestock industry
2. health concerns and/or allergies
3. dieting/losing weight
4. ethical concerns (not wanting to kill things)
5. religious practices
I'm sure there are many more. Pro-choice does not necessarily run counter to any/all of those. But even if you don't agree with someone's decision you can agree that they had a right to make it, no?
Edit: Just to add that years ago 'vegetarian' used to describe what 'vegan' now describes. But there are a lot of people nowadays that have given up meat, but not eggs/dairy so 'vegetarian' as a term has grown to largely describe those people.
Well, the thought just popped into my head because of the sites subtitle "meat is murder" (clearly someone who is vegan by reason #4) and the fact that the article deals with establishments in L.A. which people generally tend to associate with a less conservative political view.
