In the interests of boys' general development and good habits, I request that you not allow your young sons to play online games that are brutal in nature or which encourage fighting. I suspect such habits might have crept in during the pandemic to counter boredom. However, it is a natural and easy step for young boys to mistake such intended artificiality as an acceptable playing out of reality or confused humour. It is much better to play sports and join in after school activities developing health and self-esteem. Most importantly, know what your son is up to in his spare time if he is online and set some ground rules.
