Don't be fooled, she was appointed to that function just to show to the EU how liberal Serbia actually is - so that the country doesn’t have to do anything about LGBT rights for a couple more years.
I’m gay, and I'm from Serbia, a homophobic country with, currently, a lesbian prime minister. I’m not sure how successful is such an event if you need 5000 policemen to secure just a hundred people who are walking and holding banners. It takes cordons upon cordons of police to hold a Pride parade in our capital. Where I come from, the Pride parade is still a protest.
Its culmination is the Canal Parade that usually happens on a Saturday. The eventful seven days filled with LGBT arts, culture, and sports events.
