I hear what you're saying JV and I know many people go to football games with little emotional attachment to the teams playing. But going to a live game also involves being part of an atmosphere, the mood of the supporters. It's as important as what's happening on the field to me. You may not care or notice but I do. I've been to mediocre games where the fans have been worth the ticket price. It's like theatre, the reaction of the audience is part of the whole experience.
I notice a lot of people go to games, say nothing and then go home. I can't do that. I love the camaraderie of joining in with other vocal fans. I love sharing the highs and lows of what's happening on the field. I actually enjoy the singing. I'm sure this is true of the YF regulars as well. It's probably why I always enjoy games, regardless of the result.
To each their own but I still say those who don't emotionally engage are missing something. Football without emotional engagement is like sex without passion. It's somewhat mechanical.
