germany been there already... we had last week or so moletov cocktails thrown in mosques and a guy try to do a shooting with a 3D printed gun in a synagoge... its easy to assume causation when refugees come in and terror attacks increase but its more correlation, as most terror attacks are done by rightwing terrorists atleast in middle europe... we have not addressed the issue for too long and now it has grown considerably and high rank politicians were already killed by them in thier own backyard by them threatening our democracy... incase you wanna compare numbers between right extremist and wahabi terror (mostly known as islamic extremist) attacks, i did use a database to compare the amount of them... similar statistics were then published in german media later
