If Dad gets Sunday Ticket and reps Hawks at home, if the kid plays PeeWee, I doubt this stays the situation for long.
When I was this kid's age, the voting ticket was McGovern vs. Nixon. The whole block was for McGovern (this was Boulder) but my parents were for Nixon, so I was too. These days I don't have a political party, but I'm not bashful for saying why. Such an early experience makes one stick up for oneself.
Like others have said, it's less and less likely that you'll have strong parental involvement. Most parents aren't that invested in their own rooting activity. This kid can still be saved with Sunday ticket and maybe a birthday party where everyone gets a Halloween-sized Skittles bag to take home.
