As someone who is personally against bigotry, speciesism seems like a combination of racism, sexism, and ableism combined. I see no reason why someone that has the mental capabilities of a 3-5 year old (ex, pigs) should be treated the way they are simply because they have a body that does not look like a monkey, as ours does. If monkeys (homo sapiens) deserve rights and to live (as I believe they do) free of discrimination despite mental or physical differences, then why is someone to be judged on their worth for having feathers or hooves when we've already determined that judging someone on their bodily abilities and appearance is not justification for denying them personhood rights? It would be ethically inconsistent to be speciesist while claiming to be antiracist, antisexist, and/or antiableist.
