Yes, of course. At the same time, the argument could be made that your "brother" is a fellow in faith, be it Judaism or Christianity. Gentile was a pejorative term, in most cases as used, and could be treated as the situation required.<quoted text>
You are right, there are Christians who are very intolerant unfortunately. They remind me of the pharisees of old in that they see the sin in others and completely forget the core lessons of love and compassion that they let themselves be consumed by hate. Did you know that according to the Bible to hate your brother (fellow human) is the same as murdering him in God's eyes?
You have chosen the message of love out of the middle, almost literally. That is good. Unfortunately there is a lot that comes before and after. It is not Christians that are at issue - depraved people are depraved no matter the rationale or motive. But it is the institutions of Judaism/Christianity/Islam most especially that provides so many with their rationale.
On a personal level, faith can be an uplifting thing. It's when it's externalized that all hell breaks loose.
