Why is it every time someone starts a sentence with "So you're saying.." it's then followed with misrepresentation of what was actually said?

No, that is not what I said. What I did say is that in the vast number of cases when your shifting is shit it's not because of bent derailleur or badly adjusted one but it's a bent derailleur hanger. That part is designed to bend specifically so that the derailleur itself doesn't.
