I'm not going to defend the original poster, but Vienna does have some racism today, and especially against Turks.
Some of my family lives there (I have an Austrian half-sister), and when I stayed there, as a Uruguayan of German descent I never had any trouble, people were friendly and made some friends... but the son of the Uruguayan Consul at the time (a diplomat), who has some African or native ancestors and is thus a bit darker-skinned, had some trouble with buses not stopping when he was the only one at the bus stop, people being rude to him and other petty meanness.
