unfortunately the documented behaviour of the last waves of immigrants on their way to Germany does little to appease these fears
Regardless, >99% of the people who are coming to Europe right now are not future rapists.
"<1%" suicide terrorists as passengers on your B747 means you're dead.
If a society is not able to reduce this "<1%" to at least strict 0,001% by filtering and background checks, it should probably reject the remaining 99% too. This isn't fair to the rest of immigrants but otherwise it will not be fair to your own citizens.
according to whom? you don't get to claim FUD and make up bullshit in the same argument
