Certainly there are many people of all cultures and religions who are tolerant, loving and generous. But mostly to those of their own culture/religion.
As for living in bubbles, that is _precisely_ the purpose of culture/religion - to enclose the individual with a selected group, keep him/her under control and prevent him/her from interacting with outside groups. Take food taboos as an example - it's difficult to be friends with someone if you can't eat with them.
And while there may be hatred and bigotry outside of religion, it pales compared to what religion has given the world. Of course I consider most "-ism"s to be religions too.
