Actually I found being a veggie & aspiring vegan to be far more of an ethical contradiction, because when you start really learning about food production, you realise that if you think being vegetarian or even vegan means you are not a 'murderer', you are absolutely DREAMING. Thinking that just means you have no idea at all about food production, and no conception of the myriad of products we absolutely rely on that are in some way derived from animals. Just because you don't see it happening in front of your face anymore doesn't mean that our lives aren't still intrinsically linked to our livestock.
If food scares put people off the product involved - tomatoes, watermelons, the nonmeat list is endless - we'd soon run out of stuff to eat. Yes, the system can be shit, but "meat" isn't the issue.
