Are you trying to say that RT is lying and that Ukrainian fascists didn't set fire to the trade union building?
If take literally like you said - than yes, off course. They provide this material like "bloody ukrainian fascists from RS came to Odessa special for burning down holy harmless russians", which is lie.
http://tinyurl.com/m3yqfcn - here's more objective link right from the place, where you can see armed pro-russians, including guns(the very first victims of the tragedy was shotted pro-ukrainians; colorads were pretty well ready to beat the ukrainians - they know that fans will come on match and boasted in social networks before it that 'they gonna beat the shit out of ukrops'), their cooperation with police and some more interesting things that RT will never tells you. Because RT is basically made for lying in order to russian propaganda.
So, if you start to shoot other people from guns and want to beat them, you may except they will resist, they may throw rocks and molotov's and it may turn in such a tragedy. Same with Volyn, that you and Augy mentioned, he talks about 'Ukrainian insurgent army that killed and tortured 100,000 Polish and burned their villages down. Their goal was to wipe the whole area clean of all polish influence.' But somehow he didn't mention that thousands of Ukrainians died as well in the same way during that, that same actions were made by Poles in 1944-1945 relatively to ukrainian villages, also about aggressive politic of assimilation, pacification and harassment of ukrainians that were held before in this and surrounding lands. This could easily lead to such a tragedy resist, especially in time of WWII with available third parties that were not against the conflict.
Historian Mark B.Tauger has proved that the Soviet government never tried to kill millions of Ukrainian for whatever reason.
Reasons can be easily founded, if know what happens before and after the Holodomor. Btw, author of term 'genocide' define Holodomor as it.
Ukrainian "fascists and neo-nazis" - btw it is majority of Ukrainians who define its as genocide - hardly uses its to excuse their own crimes. Ukraine never denied f.e. Volyn, made "round tables" with historians about this problem, acts of reconciliation etc. and working to find out more about this - reasons and aftermath. While Commies, than RF never wanted to do anything except denying.
