The only original source linking him to the pro-Russian Ukrainians is the written drivel by Clinton’s sidekick Michael MacKay.
That’s disproved by the content of Sergio’s social media account.
I don’t think that Ukrainian separatists are normally awarded Ukrainian medals for destroying their own armor, nor are they proud enough of it to brag about it on their accounts. Nor are they painting the Ukrainian nationalist symbolic or proudly wearing the Nazi shirts on.
You are claiming he is a Ukrainian spy, not a Russian separatists. Please don't get confused with what troll position you are embracing here. In either case, his social media doesn't support you and your trolls or this random leftoid twitter user.
I understand that as a Russian who has lived in a country where historically everything told to you in the media is an absolute lie, that you are naturally prone to embracing conspiracy theories based on nothing more than innuendo and completely disconnected ideas with no logical connection.
But please, do us all a favor, and keep it on the Russian shit blogs. Leave us civilized people alone!
