No longer in the background
The thousands of illegals who have entered Europe in the last three years have created for themselves a dangerous precedent if they ever got back to Syria.
The world of Islam states that women are lower than cattle and have no rights; the problem is that if these men were to get back, they could no longer enforce that rule as the women can turn and say "Where were you when I was fighting for our country? Oh, yes, thousands of miles away!"
Of course, there is the other reason for leaving; the men are afraid that the new generation of women is not going to be content to be subservient slaves any longer.
