Personally I don't hate people saying a simple "hello", and respond generally with the same word[s] and pitch. I think it's part of the social contract - at the bare minimum - to acknowledge the existence of individuals we might encounter, and a "hello" is the most concise and appropriate means of doing so - also, in only stating a greeting, actual information remains detached.
I agree with the points made when a "hello" turns into just that slight bit more, with the addition of something such as, "and how are you?". I believe it common knowledge that people expect of this question to be gifted with a response of wellness or content, because in my reading, neurotypical individuals mirror sensations - whether positive or negative - in other people, ergo, when one responds with "Yes, I am very well", as far as I am aware, the neurotypical will then feel well. However, those of us with autism respond with the truth, always, and thus, problems can arise.
I'm fine with "hello"'s, and my universal stock reply to an enquiry about myself is devoid of as much content as possible: "I'm good, and you?". In keeping it short and rapidly re-diverting the question back to the speaker, they don't have time to really consider it. This hasn't failed me yet.
