What is wrong with this Fanbase? GO BIILS?

I would love to know why? Ever since the playoffs started, I've been seeing Go Bills posts & I support the Bills. How can you cheer for a division rival that takes over our stadium & puts a beating on us twice a year! You know, if we were in this position, Buffalo would be praying for our downfall! The only thing we have over the Bills is that we have a Superbowl if they make it & somehow win all our bragging rights are basically gone! Plus, if the Chiefs win, it makes Brady & the Patriots Dynasty look weaker. Sorry for the long rant, but all these support Bills posts have been pissing me off lately!
