I don't know what that means. European countries have multiple cultures in them.
That said, your catchphrase is typically used to imply that Islam is incompatible with Europe. But there exist several countries in geographical Europe with Islam as an established religion. Greece has an official Muslim minority. Bosnia, Albania can be classified as plurality-muslim countries. European Turkey, west of the Bosphorus has more people than many European countries. And there are sizeable non-immigrant Muslim communities all over eastern and southeastern Europe. Islam has been part of the European story for a millennium. So I don't know what the fuck you're talking about. Islam is as European as apple pie is American.
Now the Israeli centre-left is the enemy. Fascism is a death cult. If left unchecked, this will go on until they self destruct.
