The moral argument of veganism.

The only argument one can give for veganism is a moral conundrum argument based on appeals to emotion. Vegan arguments tend to focus on the moral arguments of killing animals to gain sustinance for our species. Yet beyond this argument there is really little left to defend their position. It becomes a collection of moral granstanding and rhetoric which ends up being nothing more than "i'm better than you." Lets list out the arguments to becoming vegan, demonstrate why they are important, and demonstrate how it can also be unhealthy for certain individuals.
