A very interesting article spells out how likely different racial and religious groups are to get along in the world of online dating. Among other things, the research shows that Jews and non-believers are easy to get along with, while Muslims generally are not. Perhaps surprising to some, the research also finds that Jewish men are more likely to match Muslim women than Muslim men are. To me this is actually not very surprising, especially when considering another finding of the research.
Although people can be quick to lump themselves into a particular religious group, they are often not very religious at all. These people, according to this study, are far more likely to get along with other people, even with those who take their faith very seriously. Jews make up a very broad ethnic and cultural group, and are often quite secular. Muslims in the West, on the other hand, are much more fervent in their religious beliefs.
In a nutshell, the more religious you are, the less likely you are to get along with other people. This helps explain why Western Muslims are often segregated and often demand a parallel legal system.
