No, I didn't miss a point at all. I made a point.
You and pshn80 clearly do not have the same factors that determine which teams you root for and which teams you don't. My point is that you shouldn't try to map his motivations onto yours - they are not the same.
His answer to my question of why wouldn't someone from Sacramento root against the Warriors came down to 'because tribalism'*.
I think you and I have different definitions of tribalism. It appears to me from your statements above that you define tribalism as "group membership based on proximity".
Under my definition,"tribalism" and the reasons behind one's choice of group membership (including possible proximity) are unrelated. For instance, your choice to be a member of the group of Kings fans for reasons other than proximity is as perfectly legitimate in making you a Kings fan as my choice to be a Kings fan (which
was initially influenced by proximity). Choosing to root for a team because it is close is not "tribalism" to me - in fact choosing group membership for any reason is not enough to rise to the level of "tribalism". I believe that one can be a Kings fan and not exhibit the tendencies that I would assign to "tribalism". Those tendencies that I
do assign to "tribalism" basically are of the classic in-group/out-group dichotomy - thinking such as "Person X is a Mavericks fan, so Person X must be unintelligent or a bad person" is tribalistic thinking. So is the tendency to "hate" other teams. Therefore, under my definition, what appears to be your position ("If you consider yourself a fan of
any team, why would hating any other team in that sport
not be the default?") would be at the more extreme end of tribalistic us-vs.-them thinking whereas hating only the Lakers or only the Warriors would be a milder version of the same. Not hating the Warriors despite other members of the group considering them a rival is on its face non-tribalistic to me.
That's not an argument in favor of diversity of reasons; it's an argument against it. It's a direct refutation of your statement that the reasons are and ought be diverse. That's not a "matters of taste" argument, that's a "If you're from X, you should root for these guys, because they're the next closest team" argument.
I don't believe he made that argument at all. I believe that he made the argument that during his younger days he was a fan of the Warriors (influenced by proximity) and that he still has fond feelings for them. He never said people from Sacramento should like the Warriors, he simply didn't understand why they should by default hate them. Again, the factors that have influenced his fandom are far different than yours and so it would appear are his ideas about how a fan of one team should by default consider other teams.
I do find it mildly amusing that in my eye, pshn80 is exhibiting non-tribal thinking, and you are exhibiting relatively strong tribal thinking, yet you are accusing him of tribalism. But I also think it's pretty clear that we do not agree on what "tribalism" is.
