Do you have any evidence or are you just basing your fears on feelings? Has there been a rise in sex attacks associated with this particular refugee housing?

You should flip through some newspaper archives from when you were a kid. I don’t know where you are, but I can almost certainly guarantee that there were kids attacking people back then too. Just because you and most you know would never have pulled a knife, doesn’t mean that there weren’t those that would. After all, you say the teens today attack old people with knives, but I really don’t think your teen daughters are stabbing people with knives.

How can you reasonably let your teen daughters out alone? Well, be reasonable. Find out if your fears are amped up by sensationalist press. Go meet your refugee neighbours. Quite honestly it sounds like YOU spend too much time inside.

Edit: I just saw your comment about importing men from countries where rape is natural. I can’t imagine that we have the same definition of reasonable.
