But technicalities aside - I am from Poland. Country which has every reason to hate Germans the most. Yet my opinion of Germans is that they are incredibly polite, worried to be perceived as even a little bit racist, and the part about border crossings is completely made up. Even before the Schoengen zone was opened, if you were stopped at the German border, sure, they could disassemble half of your car - but then they would put everything back together exactly as it was, and they would apologise for taking your time. Compared to the Belorussian, Ukrainian or Russian borders, where you have to be careful to not get shot.
I'm saying this as somebody grew up there. You have to ask the experience of those who actually experience the discrimination, not speaking on behalf of them. Where else in the world we have racists burning houses belong to minorities alive in 2010s? Even last year, a singer couldn't give a concert to the Turkish people there because she couldn't get a visa. If she gets visa, she may not pass the border since all the officers ask you "why are you in Germany?" and if you say you wanna travel they keep asking "travelling where?" "shopping what?" "studying what?" Now even celebs bring newspapers to show the officers to prove that they won't stay too long there!
It's a fact that being a middle eastern or being from a middle eastern influenced country let you face different attitude everywhere in the world. I'm saying this as an atheist guy who had to face it.
