I think the vegetarian argument is that while hunting may be natural for a lot of animals, including us, we have the possibility not to do it, so we should.
I don’t really agree, but it’s a reasonable stance.
Most vegans I've spoken to believe that hunting is okay. If you have the callousness of killing a baby dear, then you 'deserve' to eat it. The problem comes from how modern meat is produced - in massive factories which provide just enough conditions for the 'meat' to get produced. Animal wellbeing is nowhere near the list of priorities.
Mark my words. Two hundred years from now, if there will anything left of this planet, we will be seen as retarded barbarians for what we are doing now to the animals and environment.
