A)I was exaggerating
B)I certainly wouldn't move my permanent residence to east Germany. Wouldn't be a pleasant experience to be surrounded by people who dislike anything and anyone that even remotely looks "eastern" or "Muslim". Tbh Catholic Bavarians are already bad enough in this regard.
I really wasn't aware. Not to dismiss the experience, but are you sure it's not partially in your head? Allow me to explain, since that does sound pretty dismissive...
Basically, I feel a lot of minorities are falling for a rather heinous trap that is partially set by the media (both left-wing and right-wing) to polarise both groups and turn them against each other. They make it an issue that all people on the right hate you for how you look, when I sincerely do not think it's that simple.
I find that most (keyword: MOST) of these people (the supposed right-wing extremists) have nothing against individuals who are evidently respectful of their culture. For example, there is a guy called Mahyar Tousi, an Iranian-born individual, who is adored by the same lot who like Tommy Robinson because he's very respectful towards British culture and it's values.
I find that whilst there are absolutely racists in this world (on all ends of the political spectrum, may I add), for the vast majority, it's rarely about "how they look," and more "how they act." If you clash with the culture, people will reject you, some will fear you, and sadly, some will even hate you.
I don't think it's even a clear-cut issue either. I don't think it's fair to expect people to completely disavow and abandon their old culture, but I also do not agree with mass importing cultural values from other countries, creating pocket communities that only helps exacerbate and feed upon the fears held by many.
All I can say is... I'm sorry that you might have to contend with that in your own country.
