For example:
Carnist: "Hey, you want a slice of this pepperoni, triple cheese pizza?"
Vegan: "Sorry, no thank you, I'm vegan."
Carnist: "Oh, wow! Nice! I respect that! Yeah, I would go vegan, but I just would struggle with protein, B12, and iron if I did! Like, I tried being vegan for a week and got so sick! I still eat plant-based alternatives every now and then, though! And I totally get where you're coming from with your ethics! Yeah, the way they treat animals on those factory farms is crazy, bro! I hope those cruel practices can be abolished one day. Complete solidarity with you and the animals, dude! ✊ In the meantime, I absolutely try my best to get my meat, dairy, and eggs from local, free-range, humane, and organic farms!"
Vegan: "Okay?"
Like, seriously, just saying "Oh, okay." and moving on with your life would be preferable over this shit.
as if harvesting the fruiting structures of plants kill them.
That is not really an argument though. A good margin of what we eat is not the fruit and you directly need to kill the plant, and as with growing animals to collect milk, eggs, wool, etc, you eventually also kill fruit plants in some cases/to some extent. I'm not arguing this is comparable, plus this is a whole other level to animal exploitation
Oh for sure, I did say it's one of the worst take imaginable
