That's Ukrainian gay activist and head of the Gay Forum of Ukraine Svyatoslav Sheremet having the shit beaten out of him by neo-Nazi protesters. The protesters were angry about the gay pride parade to be held in the capital city of Kiev. The bashers ran off when they realized they were being filmed. This is what Sheremet looked like after the attack:

All of this happened as the Kiev police did not lift a finger to protect the gay marchers.

That's what happens when you dare to be out and proud in Ukraine.
