Because it affects every aspect of my life on a daily basis and just about every person I ever speak to is clueless or apathetic, seemingly believing politics is a reality TV show every 5 years. For me it's a daily event.
In this case, the people of Sunderland, including Sunderland fans, supported their own economic decline yet are seemingly more bothered by their manager. That juxtaposition is curious.
If you don't see any humour in the comment, that's fine.
Apologies if it bothers you.
