I never said you said it was the root cause, but you keep repeating that “not all Muslims are Arab” and “he was saying Allah Akhbar,” you’re clearly trying to suggest that you think the signs point to him being Muslim.
You are welcome to your opinion. I disagree. And when I said “looks like,” I was not literally talking about his appearance. That was based on the fact that he was Indian from India. And doing a quick search, apparently only about 14% of India’s population is Muslim.
