They are keeping you inside because you are enslaved. You are property. You were bred to serve humans. Any freedoms you have, you only have because the humans allow it.
If you have no compassion you won’t be bothered. Enslaving animals for medical research won’t bother you. Enslaving animals for pharmaceutical testing won’t bother you. Enslaving animals for testing cosmetics and cleaning products won’t bother you. Enslaving animals for free labor won’t bother you. Enslaving animals for human consumption won’t bother you. Surgically mutilating animals so they cannot reproduce won’t bother you. And enslaving animals for companionship certainly won’t bother you.
