This is an older clip of a neo-nazi saying racist things not far from Cottbus . . . it may be from the early 1990's, but many people in the area still feel this way

This video shows a huge group of violent neo-nazis parading through a district of Cottbus in 2008, keep in mind that many students live in this area, including foriegners

Basically, Cottbus is not a place you want to go if you have an accent or slightly darker skin . . . but of course the BTU won't tell you this and they also don't seem to care at all about issues of xenophobia in the Community, nor do they seem to care about letting foreign student know that Cottbus is a place where you need to be careful if you don't look German.
