Curious? Where did All the Refugee’s flee to during the American Revolution or the Civil War? There had to be hundreds of thousands of Cowards fleeing right?
During the American revolution, those loyal to England fled to Canada, but they probably couldn't be labeled as cowards, just loyalists.
Something comparable in today's situation would be the Syrian Alawites fleeing to Iran and the Sunnis fleeing to Sunni nations. But we don't see that; they're fleeing to non-Muslim Europe (non-Muslim for now).
