I’ll make this really easy for everyone here.
Our policies explicitly call out encouraging violence or hatred, because 1) there are just as many people calling for the untimely death of your favourite politician / role model etc as the ones you hate, and 2) there is enough pain and suffering in this world to go around, we do not need to add to it here.
I’d say there’s a very good chance that if a world leader dies it will lead to uncertainty and concern for a large number of people, at a time when most of us have all the uncertainty and concern we can fit in our worry boxes to begin with. So, the same as with the coronavirus itself, it doesn’t matter if “something good might come of it”, the BBS isn’t the place to have those discussions.
