The thing about supporting another club other than
your club is purely incidental.
My wife comes from Leeds and as a resut I often went to Elland Road with her Dad ( before we got married) and I "got to like and cheered" Leeds when apprpriate, which was not very often, I may add. I also went to watch Wednesday on occasions with her uncle in Sheffield. Thank god those days are gone and I have never followed either of them since!
Now, I watch my local team made up of some of my younger friends, colleagues or older friends kids. Now, that I can support and enjoy! Real fun clean football! real interaction with the players, a chat with the wifes on the touchline, a few soft boos at the overweight ref and a pint in the pub after the game.
So if I didn't support Spurs (God forbid!) You could say that, that's the kind of football I would support.
