I can't say I know Swift at all well. But it seems likely this normalcy is a result of the most powerful means of indoctrination human beings have ever devised (unprecedented 24/7 internet, tv, mass media establishing this "normalcy").
Which makes Swift, in her turn, a powerful agent of the same indoctrination.
Whatever Morrissey is, he seems to me far more capable of thinking for himself, far less likely to fall for/promote an engineered "normalcy".
(Which normalcy is in turn limited in time and culture. It wasn't normal in 1900 and it won't be normal in 2100. It's normal in the Anglosphere, but it's not normal in Saudi Arabia or Russia . . .)
