Meant to get the conversation back on topic and making forward progress in communicatio

It is not. If it is, then it is an indirect form of communication that is, still, disrespectful. If you want to continue to insist that my status as a bot be questioned, then all you deserve now is a proper proof that I'm a real human being.

it is YOUR responsibility to discard such non-sequitur

Incorrect. It is YOUR responsibility to not use them in the first place. Don't be the example of disrespectful conversation that we both want to avoid.

(though assuming you are not a bot

A literal, parenthetical, non-sequitur in action.

Telling you you are acting like a bot

You are not telling me I am acting like one. You are directly questioning whether I am, and in one case lament that you have to assume that I am.
