Have you ever been part of a rugby league team? This sort of thing has happened in every team I’ve played in - I was on the receiving end, I was on the ‘dishing it out’ side plenty of times, and I can honestly say it ‘being personal’ never crossed my mind, and never did I judge the other players, it’s just standard practice. And with the banter amongst the team, it’s usually more of a bit of a laugh that you’re getting flogged by everyone. It’s not personal, everyone knows that, but it’s about standards, standards that are required to be successful (whatever the level) - and it replicates a game, if you have low standards, you’re gonna get flogged by the 17 blokes on the other team, and you’re also gonna make your mates suffer…. These ‘punishments’ are to replicate those type of consequences, but also to act as a deterrent.
I’m pretty sure 99% of blokes who’ve played in rugby teams competitively will have seen similar, regularly.
