Thwn why bring up the dlfalse equivalence of school in the first place? But read the top post of this page, what I said actually happened to a fellow poster. And I don't think the OP's question is about changing teams, it sounds like the kids doesn't want to be forced to watch football at all.
I told my kid he didn't have to root for the Bills if he didn't want to, but he stayed and he's still with me at the games or on the couch every week. You don't like my way? Cool, but opinions are just that.
