I think Serbia's bad rap is often unfair. Sure, they have a massive problem with nationalism, and they still haven't got over that losing in war thing, but Serbs these days, excepting right-wing extremists, seem to just want a normal life.
That said, the bad rap is sometimes completely justified. Gay rights are one of those cases. This year, Serbia had its first gay pride parade since 2001 (the last time riots were so severe the pride parades were discontinued). Didn't turn out so well.
Quoth the BBC
Rioters threw petrol bombs and stones at armed police, who responded with tear gas and rubber bullets.
The office of the ruling Democratic Party was briefly set on fire, and at least one shot was fired.
Calm was eventually restored but more than 100 people, mostly police, were injured, with another 100 arrested.
Fortunately, though, the authorities seem to have had enough of hooligans tearing the city apart, looting, overturning cars, and serving Molotov cocktails in a fit of pique over other people's sex lives. Quoth The Guardian
Dragan Sutanovac, the defence minister and vice-president of the Democratic party, said part of the party's archive, warehouse and phone lines were destroyed.
"It is high time that we deal in a very democratic way, through the courts, with those who call themselves members of the patriotic organisations," Sutanovac said. "Is this Belgrade or the wild west?"
Slobodan Homen, a senior justice ministry official, said the state response would be fierce. He said the rioters had been identified using surveillance cameras in the city centre and could face up to eight years in prison.
Serbia will have to deal with this sooner or later, of course. Not only if it wants to join the EU, but because such a reaction by nationalistic groups tends not to make for a stable state. It is also instructive: Sure, supporting extremist sentiments may help you gain and keep power, but, as the saying goes, if you lie down with a dog you get fleas, and this dog is rabid, to boot. There are always consequences, and you may not be able to control them.
In short, such groups really shouldn't be encouraged by anyone. Some time, some day, it can bite you in the arse.
Oh, yes, my hat's off to the police. Intervening is riots is probably the most thankless peacetime job you can get. And the number of injured policemen (I think the final tally is 142) shows how violent that thing was.
