Unless you're a fan of the team already living in a market that they move to, I really don't get how any fan would still support the team they rooted for after they directly told you to **** off and left you for other fans instead.
So, any Raiders fans that already lived in Vegas or the three Chargers fans that lived in Los Angeles or if someone in Nashville is a White Sox or Brewers fan? Sure, still like your team that's now moving to you. But the fans being abandoned? I can't imagine still supporting such an egregious middle finger to a) you, b) your friends and family that also rooted for the team, c) your city and metro, and d) the team's entire history.
But it won't matter, Sox will get bought by a Chicagoan. And if the unthinkable does happen and a new AL squad moves in a few years later, it’s perfectly okay for them to now be your new team.
