I'm a Vegan. For all the reasons most vegans are vegans. Yet I still happily feed my snakes and reptiles rats ect. Why?
Because I'm intelligent enough to realize that different beings have different needs and desires. Just because I choose to live a certain way, doesn't make me right or others wrong.
Anyone who complains for the 'greater good' is generally a keyboard warrior, and its all smoke and mirrors. I live as a vegan because I respect my body and the living. I feed my snakes mice or rates because I respect theirs.
It's not rocket science.
