This was not a very smart moment by Bismarck, I have no idea what he was thinking when he lifted the Munster player. There is no reason why he had to do it and there was clear intent when he lifted him. I'm 100% okay with stuff like this being red carded, this is why context matters. In this case there was clear intent shown by Bismarck. It was a dumb decision that almost ruined a good game between the Bulls vs Munster, I can't imagine his teammates and coaches being happy to see him do that. This decision was so obvious that even Ben Whitehouse couldn't mess it up, despite being one of the worst referees on the planet. This is clearly much worse than an accidental head clash, yet World Rugby sees both incidents the same. They can't differentiate between the two and they don't care if one is a rugby hit and the other a clear case of foul play, to them it's the same if there is any contact to the head, which makes no sense at all and is killing the game. I'm also not a fan of the red card in general, I think it ruins the game. I still would prefer if a player gets ejected from the game and they can suspend and fine him after the game if he does something egregious. However, I do believe a team should be allowed to replace that player after 10 minutes which would make the games much more entertaining than just simply punishing a team by playing 14 vs 15. Hopefully common sense prevails and World rugby sees the obvious flaws their policies and start making changes to it, but the chances of that happening is probably zero.
