Re: I know this is article just part of the anti Russia propaganda
Clearly, my attempt at an example failed. I'll try again, attempting to be more concise this time.
Whataboutism is a cheap way of not answering a question by bringing up some other topic. It is likely that the other topic is worth discussing, but it's only brought up in order to throw discussion off the original question. As an arguing tactic, it's on par with an interviewee who simply refuses to listen to a question and starts talking about something irrelevant, but it's a more subtle version and thus is more often accepted.
In this case, the comment that got us into this was about western surveillance systems. That's worthy of discussion, and I think we all pretty much agree on our opinions towards it. But nothing specific was mentioned about the systems that connected to the topic under discussion. Instead of talking about the original topic of Russia's new law, or making an effort to compare it to a western system with which there are similarities, the issue of western surveillance was just dropped into the thread. I don't think it was done intentionally to distract us from Russia; I think it was just a comment that didn't include enough context on why it was important, but the effect is to send the discussion off course.
