Love?

I believe in a God that is love. A God that asks us to love others as we love ourselves. And still I see many who claim to follow this same God that express hatred for people who live lives that are not necessarily what you would see in the church daily. I don't understand how they can be professed Christians and still not love others as Christ loves. Maybe this is me being judgmental but I am just trying to call it as I see it. But I believe deep in my heart that God wants us to love others no matter what because when Jesus walked the earth the people that he hung out with were the people that society shunned. Just thoughts I wanted to get out there.
