There is an old, possibly apochrypal, story that goes like this.... back in the 1970s in the early days of "The Troubles", a bunch of people in East Belfast appraoched a hindu temple and knocked on the door. An eastern gentlemen answered and asked how he could help. The leader of the crowd said "We need to know what side you're on. Are youse protestants or catholics?".
The gentlemen smiled and said, "We are Hindus".
"Yes", said the leader, "we know that, but are you protestant or catholic hindus?"
That just about sums the place up. It hasn't changed much, but your obeservation that they treat foreigners better than each other is spot-on, 100% accurate. Foreigners are forgiven almost any indiscretion, after all, they don't know any better......
