It's hardly argumentative to suggest that people who attend game's week in week out are the most loyal supporters.
How'd you start following Man Utd out of interest?
Because being a supporter isn't about watching games in a pub. Its about going to games, singing, enjoying the banter with rival fans, travelling great distances to watch your team.
But If you're just a guy who shouts and roars at the TV in a bar and starts fistfights with randomers, that doesn't make you a hardcore supporter, it just make's you an angry man in a bar or at home on the couch. You can say to yourself all you want that you're as much as a supporter as the guys who follow Madrid/Juve home and away and across Europe but it doesn't make it so.
And believe me, I'm in the same boat as you are. In addition to supporting CCFC I have a fondness for Aston Villa which means I watch all their game's and go over to Brum frequently enough during the LoI offseason, does that make me a supporter like the guy in the Holte End who's had a ST For decade's, sings his heart out, follows Villa up and down England and has basically lived and breathed Villa his entire life?
No, no it does not. Sorry if that offends you.
