I should like to say it isn't possible, but I wouldn't put it past them. Where I am from, about two hundred years ago the muggles decided that we were such a threat that they would kill us. Murder every one of us, down to infants just come into their magic. Eventually we had to go into hiding, and now many of the muggles don't even know that we still exist. But we are safe from them, and our society flourishes. Your people will find a way, too.
I say, you do know how to make a fellow feel better about being here.
