Recently DS went to a football tournament in a different city. He and DH tell me that some boys were swearing (calling others fucking shit), punching, kicking barriers. The person in charge tried to keep on top of it but the swearing kept on happening. Parents were present but oblivious.
DS was upset but then he is a sensitive child. I told DH he should have taken DS out of the tournament as soon as one of the boys chased another out of the field and punched him. DH disagrees, he is happy that DS stuck it out as he needs to toughen up. I think that DS has plenty of non-sweary, non-punchy football mates so he doesn't have to put up with violent kids. Who is right? For background DH is British and I'm not, he says "British football is like that". So:
YANBU - nobody has to put up with violence and swearing if they can help it, and that includes children. Getting your kid out of the tournament quickly would have modelled setting healthy boundaries.
YABU - boys need to toughen up and not let a few words get to them. It prepares them for real life. Football is like that anyway.
The boys were primary school aged if that makes a difference.
