I wouldn’t be surprised if this outrage is astrotrufing from righties because they’re scared how powerful Swift is in mobilizing Voter registration for the left.
Someone else pointed out there was a John Oliver segment about carbon offsets (in which he pointed out that they aren’t well regulated and are subject to abuse.) I think people forgot the specifics and just remember OFFSETS = BAD, rather than the appropriate albeit more nuanced “like most things, these are vulnerable to abuse and should probably be better regulated.”
Combine that with hating mainstream pop culture with a chance to condescend and you have a perfect storm of toxicity.
