Don't be sorry mate, I feel exactly the same as you, except my reasons for not becoming a member are location based, not financial.
Everyone here supports the club/team in their own way, and it's not for other fans to judge whether they are right or wrong. If you say you're dad has been following the team since the 70's but is not a member, does that give him the right to be vocal about changes or be critical? f**k yeah it does!
It's holier-than-thou bullsh*t attitudes like "I've paid my membership so I deserve better" people that need to realise that they're more or less having their cake and eating it too.
Couldn't have put it better myself.
My dad got me started on the Eels about 1970. He still follows them through thick and thin, like we all do.
He's in his late 70's now, and everytime we talk, it's always about the Eels. 3 times a week at least.
He's never had a membership though, just a season ticket for one year - 1986.
He must be a really crap fan judging by that.
Suity
