We have an Arabic guy that visits our parish sometimes. I have to admit, it took me aback for just a moment when he raised his hand to heaven and loudly said "Allah!" But then I remembered ...
When I mentioned it to my husband, he was a little surprised too, but I explained it to him. A lot of people don't know ... maybe there's a kind of hyper-vigilance against Muslims too. But then again, if you explained ...
Sorry you had to deal with that.
I get a little frustrated when people argue what they don't know too ... and usually they don't WANT to hear the truth??? That's what's weird to me.
