Vegetarian who enjoyed your post here. I found your arguments well reasoned, the main sticking point to me was the marginal case argument. I would argue that our preference for and able to differentiate other humans over livestock does not defeat the logic of the marginal case argument. However, neither of the arguments you presented are the primary reason I am a veg. I hope you will consider addressing the environmental impacts of animal husbandry, I'll be there for the discussion if you do!
I enjoyed your post and included it in today’s #philosophy-review
