And apparently there are less stupid reasons as well. Though I am inclined to ask, do you always refuse to eat animal product or is it more of a "my diet is generally vegan" scenario?
My diet is exclusively vegan. I see food as fuel rather than as some hedonistic pleasure - I'm a rather thin man as you might imagine - and after keeping a vegan diet for so long it just becomes a hassle to deal with meat or dairy. I don't really digest animal products that well anymore - meat isn't appealing to me and dairy is mucus-producing and just... kind of gross to contemplate eating.
That having been said I *do* take 2 nutritional supplements that are derived from or comprised of animal products: Omega-3 fish oil capsules from Nordic Naturals (a brand I think is high quality and Consumer Labs, which I subscribe to, supports) and Vitamin-D3 which is the more bio-available form of Vitamin D. I do this because I get very little sunlight being a typical cave-dwelling gamer type...

- though I exercise on a regular basis it happens indoors or when it's overcast or at night. I don't like the Sunlight much at all. The fish oil is more for cardiovascular benefits and as a nod to the fact that some vegans have deficiencies in fatty acids found in fish; then again, so do many omnivores who don't eat fatty fish on a regular basis.
So I suppose you can say that while my diet is entirely vegan I do consume minuscule amounts of animal products in the form of a fish oil and a vitamin supplement. Otherwise, I find eating flesh and dairy distasteful. I don't believe that "eating" animals is cruel, but I do believe the factory farm conditions of animals kept in at least the US are needlessly cruel and somewhat disgusting. That having been said, I see nothing wrong with, say, a farmer killing and eating his own organic meat and eating his own organic eggs.
I hope that clarifies my position a bit.
