There's a lot of middle ground between getting upset at people liking non-football sport and people thinking American football is particularly shite. I often watch boxing, tennis, athletics (plus snooker, "sport" status tbc); watched ski jumping and egg chasing over the last few days.
American football is definitely on the shite list, along with golf and test cricket. But apparently Taylor Swift was playing this year so it needs to be in the news, and talked about by bell ends at work, which is irritating.
