Let's just call it for what it is. The argument from a "certain side" of the fan base just lacks any form of critical thinking. It's an incredibly simplistic viewpoint of "These are good players, why trade them, build around them!" but of course that viewpoint leaves out important context like 1. Who the owner is 2. How far away this team is from competing 3. Contract values and length of term and a host of other factors. Some people just don't want to educate themselves on another viewpoint. Not even to change their mind, but to simply understand the other perspective. Greg said "What's wrong with Robert staying on for 2-3 years and making some memories on the South Side?" When users try and explain that no one wants to stay on a perpetual track of losing, but instead build something sustainable, users like greg simply can't grasp how trading Robert can accomplish that. They can't see the forrest through the trees.
The biggest disconnect seems to be users like greg seem to think fans want to get rid of someone like Crochet. Because fans are obsessed with a new shinny prospect. When in reality, 99% of White Sox fans want to see Crochet on the White Sox for a long time. But as noted above, fans are smart enough to know the current owner of the White Sox won't pay for a contract extension for Crochet, and given where this organization is in the rebuild process, the next two seasons won't see the Sox contending for a playoff spot. So knowing he won' be re-signed, and the Sox won't field a team around Crochet that can compete while he's under contract...the choice to move him while his value is high seems like an obvious one, but I guess not for some.
Lastly, there is something to be said about fans in their 60's, 70's and 80's. Anecdotal, but in my experience both on this forum and in real life, in talking to those Boomers (not a put down) they just want a slightly competitive team. I don't know if it's a "closer to death" thing, but most can't seem to wrap their head around a "tanking process" that will take multiple years, it just doesn't make sense to them and will never accept it, even if it's a harsh reality for most teams in most sports, and has been shown to work.
