There are a lot of things that I was taught growing up that I used to sort of just accept but from the outside don't really make any sense (as an example: where I grew up was pretty homophobic but once I was old enough I realized that the homophobia just literally made no sense and it was stupid to care what other people did). The current state of animal agriculture is one of those thing, growing up I ate meat and I had all these justifications but once I stopped I realized it was all bullshit and the treatment of animals just wasn't okay. It's pretty crazy the way we'll just accept things that are "normal" even if they are absolutely horrifying.

The saddest thing to me is the people that say they "love animals" but eat them pretty uncritically (though obviously I used to be one of these people).
