Be careful, you can’t tell all parents to shut up. Sometimes parents fund multiple players on your team and it will collapse if you do such a thing. #RollRats
You any tell people to shut up- you are supposed to be an adult who can change the topic of a conversation. I can’t stand a parent on my kid’s team, i grin and deal.
People who do this tend to be anxious about their place, perhaps they had a bad relationship with their parents who the f knows.
We all have one or two, keep in mind everyone likely feels the same way about them.
