I’m not sure anyone can achieve much on that front: various forms of Christian hate and kill each other, as with some Moslems too. There are quite a few of the latter go to my local bar, and they are no different to anybody else: polite, say hello, and have bought me a coffee, and on one occasion, when I walked the klick down to the shops and the bar, thinking it would remain cool, I discovered my mistake a couple of hours later when I started the walk homewards in high heat. As luck would have it, one of the guys I was writing about stopped his van, told me to jump in, turned around and drove me home. That was a helluva kind thing to do for an old guy who should have known better.
As with much in life - you get back what you put into it, and sometimes not.
