Attacking the source of this article and the country of its origin contributes little to the conversation.
Opposing viewpoints, media bias (intentional or not), nationalist issues etc.
It is just as fair as calling into question a story from Iran's Press TV.
Russia Today is exceptionally critical of American politics, and their international video newscasts are pretty much dead center criticisms of America. They barely mention Russian affairs, if at all. Whenever I catch a glimpse of them on MHz WorldView I have to change the channel.
Every time I watch RT, I can't help getting the impression that it's on a mission to criticize and attack the US at every opportunity. All this, while ignoring far more egregious crimes within Russia itself. It's blatant, unashamed hypocrisy.
