Hardly you can say that muslim leaders are religious radicals, but rather just terrible dictators. You can't say Asaad, Erdogan or that king Salman are religious extremists lol.
About ways of life being respected or not, I'd say it's a request that has no sense if you're disturbing the life of the community you're in. Just like when some muslims complained about the Hijab law in France.
While the hate against you personally is unwarranted you must understand why this German hates you. You're associated with a religion that has brought nothing but terror to their country and continent over the past year. The bigger issue here is not the fact that you were discriminated against but the fact that Islam is essentially colonizing the West.
Untrue, you can't hate anyone because of it's religion lol, it's not acceptable. And while there was problem with refugees in Germany, the gvt hasn't acted to punish them with the rigor it needed. Islam isn't colonizing the west. If Europe accepted all the muslims seeking for refuge on it, the total ammount of muslims in Europe would raise from 4 to 5% WOW, such a colonization lol. The truth is that those refugees are fleeing from the war the West started in the middle east, we should accept them, but also press muslim countries on the region to accept refugees as well. The golf monarchies didn't take any refugees while they're also accountable for the actual instability of the region.
