As someone who has had Brewer (and Packer) fandom in my blood from birth, but has lived 30 of my 31 years in Illinois, I can speak to this phenomenon. The attitude you sense is not just an online thing, it is very real among flesh and blood interactions, too. I live in a part of the state that isn't particularly close to Wisconsin, and is in fact about half way between Chicago and St. Louis, so I have seen this from Cardinals fans, too. The Cardinals fans ("Greatest Fans in the World, and Keepers of the One True Right Way to Play Baseball") are obnoxious for their self-righteousness, yes, but they've earned it. They have the pelts on the wall, and so while their thumping of the unwritten book of baseball rules and their general snobbishness still rankles (and boy, 2011 absolutely killed me--my wife is a Cardinals fan!) I can at least begrudgingly respect where it is coming from. Cubs fans are a different breed entirely. I know a few decent ones who will hold a respectful conversation about baseball and not allow themselves to be too blinded by their allegiance as to be insufferable. But I only met them well into my adult years. The vast majority of the Cubs fans I see in their native habitat have been boorish, ill-informed, and take pleasure to go out of their way to tell me that my beloved franchise pales in comparison to theirs and that I am a fool for following them. This was true even in the 90's when the Cubs had some truly pathetic teams, and apart from a few years of good play, were often just as pathetic as the Crew. I have always been surprised by this, since if the Brewers win a World Series title soon, it would make them about as successful as the Cubs have been since baseball returned to Milwaukee, and with a better stadium, to boot. I was surprised, that is, until I realized it boils down to tribalism and a bullying mentality. Cubs fans outnumber most of their rivals, particularly in the heart of the midwest, and so they gang up on and belittle fans of smaller franchises, and this gives them an immense pleasure, often irrespective of actual results on the field. As others have mentioned, for some, this is a class issue, since Cubs fans (particularly in Chicago proper) are far more affluent on average than your typical Brewers (or even Cardinals) fan. As this pertains to Miller Park attendance, that isn't the only issue, but I suspect it is a big part. It must be awfully tempting for many Brewers fans to flip tickets to Cubs fans who are willing to pay a premium to see their team in a more comfortable environment than the "friendly confines." Heck, I can even sympathize with those who see these brutish louts invade Miller and decide they'll spend their hard-earned money on a different matchup, especially if they are bringing kids to the park and don't want to expose them to the generally appalling behavior of many of the Cubs fans. But I can only speak for myself when I say that when I watch the Crew on TV (I get FS Wisconsin and try to make 2 or 3 games a year in person) and I see the Cubs fans in attendance, I see the same bullying attitude I saw growing up in this state. If I am ever fortunate enough to live closer to Milwaukee, I will make it a point to attend as many Miller Park Cubs games as I can (although I'll probably leave the kids at home), and gladly cheer as loudly as I can. At the end of the day, the Crew is about family to me; always has been, and always will be. The only real Brewers fans I've ever known personally have been my late grandfather, my father, and my uncles. Of that group, the only one I have close enough to regularly converse (read: commiserate) with is my dad. Although I have been incredibly happy to find brewerfan.net and all you fellow-sufferers as a makeshift community, I've always been acutely aware of the fact that I don't really have a "tribe" of my own. I hope my dad and I get to see the day when the Crew gets to celebrate on the field as champions of baseball. No words of vindication need be said, even after a lifetime in the lion's den; we can just look at each other in that moment and know. And we could go back out into the world and be at peace, not to be as the Cubs and Cardinals fans have been, but simply to smile and to know the feeling was sweeter than they could ever imagine. It would be a great feeling... ...but beating the Cubs and/or Cards on the way to that moment would be pretty sweet, too...
