Having been to the "dirty Balkans", I would point out to this Dutchman that cities like Split, Dubrovnik and Sarajevo are cleaner looking (and safer) than many cities in Britain. 

I know some Dutch people from the Netherlands who are incredibly racist towards Slavs, but amazingly they have 0 problem with Africans and Asians.  Much like racist British who complain about Poles but turn a blind eye to East Indians (who easily outnumber the Poles 3:1 or more in London), it's just Western Europeans being idiots.

Even in North America, even though people here are not good at distunishingly looks, people here can be very anti-Slav too.

Most of these people know their societies are on the decline and Slavs (minus Russia) are not disappearing.
