RT is a well-known Russian propaganda operation. The fact that your response to it was "it never was anything that gave me pause" is a sign that you did not detect the propaganda and that it may have been working on you.
Could be, or not considering I've never read an article from them and couldn't name a single headline (which is why I asked the question)
The state news agencies are only problematic as sources when they are writing about their own government or immediate enemies... in that they will tend to prefer publishing what their leaders are saying vs what the enemy is saying about them.
So the next time a giant scandal about Anonymous's secrets is uncovered or if the BBC airs something that Anonymous doesn't like in the UK, maybe they will run a DDoSing tool against them?
Almost as if every other news network and media company is not a propaganda operation meant to serve interests, and RT is the odd one out.
