criticizing doesn't equal hating?

Critique/rants have always existed in creative media, such as movie critiques or general discussions/debates about the story. Why have we gone backwards to think it hating? As long as they're not harassing the author or readers who like it there no problem. In fact you can like a story and still criticise it. I'm literally obsessed with secret lady/htgmhoms and a major one-piece fan but I do find myself sometime criticizing small stuff about them.
