Here is a quote from DMN that helps explain why Hamilton is being booed even more:
"At game’s end, fans chanted “Baseball Town! Baseball Town!” Hamilton smiled and made-believe like he was throwing a football pass to them."
Hamilton is mocking the fans on purpose. He loves to mock Rangers fans and bring attention to himself.
He started the entire bru-ha-ha with his smart-*** remarks about this not being a baseball town. He craves the attention and won't stop needling Ranger fans. I've come to the conclusion even his wife made up all the stuff about needing extra security. No one was ejected from the stands and all we saw were the same kind of good-humored taunts that Hamilton started.
Hamilton started all this with his trash-talk following some understandable booing. He trashed the Ranger FO, the fans and the city. And he refuses to apologize, instead making things worse ON PURPOSE to get as much mileage out of this as he can.
The booing was a completely normal and understandable response to some very crappy play. Pujols was booed last April. It's normal stuff when someone does so poorly in the field. Hamilton makes it all worse with his smirks and flippant remarks. He should have said "It's understandable why Ranger fans booed because it's not like I had my best days towards the end of that regretfull season, and for that I apologize and can only work harder to make sure it does not happen again, for the fans, front office and owners who are so gracious to give me this job."
Instead he blamed it all on the fans. Then he blamed the front office for him leaving. Like many alcoholics, he's a blamer and does not take responsibility for his own actions. And like many alcoholics, he's a drama queen who brings attention to himself while not recognizing the feelings of others.
At this point we can only assume he's doing this on purpose for the attention it brings. It's gone on too long. By now he knows it riles up the fans. Yet he keeps doing it. He can't hit a baseball anymore, so this is all he has left to stay in the limelight.
