Anyone who would even contemplate in possibly joining up with these 7th century backwater murderers is someone you wouldn’t want to have as a neighbor.

“It is completely unacceptable that Swedish citizens are travelling to [join] IS, financing the organization, or fighting for it,” Justice Minister Morgan Johansson and Home Affairs Minister Anders Ygeman wrote in a joint article in the Dagens Nyheter newspaper.
The proposed ban would prohibit combat for terrorist organizations listed as such by the United Nations or European Union.
“We have a responsibility for what our citizens do both here at home and in other countries,” they wrote.
“People who live here and who have chosen to join IS can constitute a serious threat upon their return. Criminalization is of course not the only way of preventing this, but it is an important part of anti-terrorism measures,” they said.
