Dave, I would suggest that you are drawing a general conclusion to match your prejudices from a very small sample which constitues an exception rather than the rule.
Australia's most prominent Islamic cleric, Sheik Taj Din al-Hilali, said he had heard about girls who had been taken to Lebanon for arranged marriages, a practice he condemned as "unfair for the children" and against religious teaching.
"It's against Islam," he said. "This is cultural thinking, not religious. "They (the parents) want her (their daughter) to be safe, and to bring the families closer together, but these marriages are not true and are unfair for the children."
I would also suggest to you that much of this cultural thinking is from first general islamic migrants and that subsequent generations will not have the same views. You need to try to look beyond your prejudices
