>People need to consume what their body needs, that will keep them in the best state of health.  And people's dietary needs differ.  For me, while I enjoy the capability to be an omnivore, having tried to be vegetarian in the past greatly wrecked my health, and that would mean attempting any type of vegan diet is absolutely not doable.  So for me, meat is a very necessary part of my regular diet.

This is probably going to end up in a bit of a dead end. But, I don't believe you. From my experience of people trying and failing plant based diets, they usually did stuff wrong. Did you have your blood work done after a year or so on one? What magical nutrients can you only get from animal sources? 

>Everyone has to address their own needs in their own way, so for me there is no real aspect of morality involved in my diet (other than certain Buddhist precepts/ethics).

Do you minimise your intake of meat to any significant extent? Even if I were to grant that you needed some, is it still possible you consume them in excess purely for the pleasure? 

Also, do you buy other animal products like leather?

Edit:

It's not clear to me that you've answered my previous question. If you're going to complain that vegans eat vegetables that result in stuff like crop deaths, what do you eat that minimises death to a greater extent?
