This dad caught his son's reaction when he was told that he couldn't root for the Yankees.

The little boy gets so upset when he's told that he's not allowed to root for the Yankees. His dad said that he was trying to teach his son a lesson in loyalty because the rest of the family are a bunch of New York Mets fans.

Sounds more to us like he just wants his son to be a Mets fan. Loyalty is built, not forced. You're just going to make the kid hate the Mets more than he already does.
