Okay, let's set the record straight: if you eat meat, you're a monster. Period.
Now you're allowed to be a monster if you wish. Be know that people have a right to slap it right back into your face, and remind you that you are the cause of this world going to hell.
But you're definitely allowed to be a monster, as I would be one as well if I tried to prevent your heart from its selfish desires of destroying our ecosystem. I'm not a monster, so I'll reluctantly allow it.
