The Intrepid hate was nowhere near as bad as the Anson hate is. Intrepid's design had plenty of defenders with many pointing out that it was just her head that seemed kind of off and others even went so far as to point out that being somewhat generic was very much in brand for a member of a 24-ship carrier class.
Anson hate, on the other hand, is rather overwhelming with defenders finding their takes incredibly unpopular unless they concede that she's not supposed to be a KGV-class. Hell, you even had a certain handsome devil point out that this belied a massive structural problem with Yostar and get away with it despite how controversial "his" Azur Lane hate was at best.
People also didnt like that the loli looked like a reused artwork of a submarine. And probably because people really dont care about Destroyers but they do care about Capital ships meeting their expectations, thats why she has the oversized rigging, but somehow they missed the mark with the rest of her design.
