There is a difference between keeping peaceful relations with your neighbor and befriending them though. You said yourself they are not likely to change their mind. If that is true your friendship does nothing to help marginalized folks. In fact it hurts them since your friendship is a tacit endorsement of their behavior. I'm not saying yell and scream and throw stuff at them when you see them, but there is a difference between cordial neighbor and friends. If you really want unity and kindness, you can't tolerate hate.
