This culture first thing over Islam among many muslims is like a disease. I wanted to marry a muslimah that I had known for 4 years. Her father and brother knew me and had performed salat next to me at the masjid many times. When I sent a brother to talk to them on my behalf. They said No and refused to meet with me. Because I was not from their country or their tribe; plus, I was of a different race. It was a devastating experience to say the least.
Just being muslim isn't enough.
