Yes, as a German, I would be totally avoiding this person, as I rather be safe than sorry, instead of being dead. It has nothing to do with racism, this is a pure survival instinct. I'm pretty much a lefty (even though I would rather want to be called as such, but I have no other choice, as I definitely don't want to be called a righty.)

However, take this with a grain of salt, as I am living in a village and have to do with such people more; because they rather get 'transported' to less populated areas; thus are higher in percentage of total population.

There are some of them out there who fit in our society, but just as many as I've seen such, I also saw the opposite. Like I said, no racism, but rather a safety measure.

Because, after all, this Arabic text is a sign of not being able to take part as a person in the German culture, as they're still using items and their language in a country whose it is not spoken or learned as a second language.
