isn't it the case that this person made this post on their own Twitter feed? Rather than standing outside your living room window shouting it at you or posting it on a pamphlet through your letter box?
No. It's on the BBC Social twitter feed.
So the question really is, why are you giving it such attention? And such fury
I haven't noticed any furious posts. If you think most people are commenting in fury then I think you may need to accept you don't judge tone well in text (which is not always easy).
Why are you commenting on people's comment? Why does anyone discuss anything on MN? This is a public video, produced by the state broadcaster to put forward a particular viewpoint. It's entire purpose is to generate discussion (even though it is not in a pamphlet).
Perhaps a better question would be Why do you criticise people for disagreeing rather than explaining why you think the video is right?
