It's not only about religion & culture, very few middle eastern women interracial marriages were successful over the years. In particular, women from the gulf. It all end up badly, regardless of the parents consent.
Take for instance the story of Mariam al kalifa , the Bahraini princess who choose to marry a marine and fled to the state in 2000
http://en.wikipedia.org/wiki/Meriam_Al-Khalifa
She end up divorcing her husband and returned to Bahrain. Despite of all that media circus
There are many stories like this, as I've written earlier the ministry of welfare has a dedicated section to deal with Qatari women & and thier offspring who live on welfare. Many of those cases are of women with failed interracial marriages
Of course people mindset will not change, with their perspective of those marriages been proven as a failure in most cases
