What a load of crap. It's certain to call what beastmen suffer as a form of racism. Racists don't care about the truth, they manufacture lies to have superiority and enjoy the suffering of the others. They'll not stop because who they oppress are being good and pacific. So, it's only right that they react with violence, it's self-defense. That's not gonna turn prejudice in truth, because prejudice will always be based on lies.
And also you want me to believe that using the beastmen as scapegoat was some necessary evil for the greater good? Bullshit!
