When men are shitty to others: men need to educate other men on how to be better
When white people are shitty to others: white people need to use their privilege to educate each other on how to better
When humans are shitty to other species: Don't shove your beliefs down my throat! Torturing and murdering other animals is just as valid a lifestyle as not doing that!
(To be clear, in all cases where a group you're in is being shitty, even if you personally are not, you should speak up and try to correct course. And that includes animal abuse)
