okay that "plantkin" thing reminds me of something I saw a while ago
http://ace-pervert.tumblr.com/post/132221024963/kill-all-carnivores-you-must-be-a-loving-moronsome backgorund + quick overview of this argument:
the first guy (ace-pervert) made a post where they said "kill all carnivores"
normally I would assume they were just hecking with people, like that kinda stuff usually is
but theeen ace-pervert got into a whole argument, where they apparently specified that there is a difference between "carnists" and "carnivores", "carnists" being people who eat meat and "carnivores" being regular predatory animals
and you will remember that they said "kill all
carnivores"
so this person has no problem with animals being caged up and slaughtered and junk, no, the real issue with the world is the wild animals (or even domesticated dogs and cats for example) doing what their instincts are telling them to do
which is a very misguided opinion
