Some of those are harmless. The "beautiful day in NYC. . ." tweet seems to be parodying gay marriage opponents, insulting celebrities isn't inherently a big deal, etc., etc.
She clearly, though, had massive blindspots when it came to trans issues and slut shaming. With the former, it's clear transness was at least outside her comfort zone, and her understanding of it crude and marginalizing; with the latter, she was straight up hateful, feeling free to call women whores and directly shame them simply for the sin of promiscuity.
It's not particularly surprising, honestly. Her has-it-togetherness always seemed to have a certain traditionalism to it, a certain capacity for judginess, and the combination of those two rarely comes without some baggage. I'd hope that, in the time since those tweets, she's expanded her bubble, sought out understanding, and put some of her more misguided impulses in check.
