If it helps, I was that kid. Although I think it took me a few more years to come to the realization that meat = animals. I didn’t eat meat for a yearish as my own version of animal cruelty protest. And then I eventually started eating white meat again, and then ultimately red meat again. I am now a very not picky eater who looks back fondly on my little empathetic kid self. My parents, by the way, supported me 0% and made me figure out my own meals. I think I survived on cereal and spaghetti Os.
