that's the problem with European people, you're always staind Arabs backs, even if they put a knife in it.
it's time to wake up these people doesn't like us, they came in our country only for the money, if one of us goes to their country for 'vacay or something' he got his neck cut.
you know my cousin dating a Turk never had problem with his family but the day that she become pregnant his father came mad, he said that he gonna go to the hospital and cut my cousin and her baby neck!
the boyfriend of my cousin dosen't talk with his family for years after that.
1) Are we talking about arabs or muslims ? 'cause most muslims aren't arabs an, even if ita minority, some arabs aren't muslims.
2) My brother married a muslim girl, everything went (and still goes) fine, there had been 2 religious ceremonies one in church and one in a mosque, both of our families attended both ceremonies, etc...
Your cousin's in trouble with his girlfriend's family because they are morons, not because they are muslims.
There are families that refuses their sons and daughters (but mostly their daughters) to marry someone from another religion (or an atheit) in every religions. And there are also families that are open minded and agrees to accept peple from other religions if their sons or daughters choosed this person to be their wife/husband.
This is not a question of religion, this is a question of morality, this is about being open-minded or close-minded, about accepting people thar are different or not accepting them.
