Unfortunately, in a democracy, you don't hold a referendum on topics that would be inconsistent with the constitution.
Constitution is not a suicide pact. Without numerical limits, it is.
Asylum rules don't include country shopping. You cannot ask for asylum from a country where you are already safe.
In case this concept is too hard for you to understand...You can't ask for asylum in Germany from Spain, for example...
Finally, you must apply for asylum while still outside, not after you illegally entered Germany.
This allows Germany to say no if you don' qualify.
Once inside, Germany has to go through the expensive process of deportation - with lawyers and multiple hearings while on German welfare.
Is every Polak an idiot?
