Humans are tribal and following a sport is just another way we get to be with a tribe.
I never got it.
Like all this crap about being a Manchester United fan. What is the point? It's not as if all the players come from Manchester. It's just a manufactured/paid for team with no real roots anywhere any more.
What is it you are supporting there? A multinational company listed on the UK Stock exchange that sells lots of seats/merchandise and uses that money to pay a bunch of jumped up, self obsessed, overpaid, spoilt pricks to kick a ball arond and take a dive (cheat) whenever the opportunity arises.
Fuck that.
