I think there are multiple factors in play. I think the biggest one is guilt by association with Allen. I think some people can't see Carr as anything but an extension of Allen. There's also a lot of personality bias in play. Carr has a bit of an Oddball (intentional capitalization) personality type which some see as disingenuous and phony. Then they got all into those negative waves about him feeding his children at Chipotle when he and his family first got into town.
