Nick, these are genuinely interesting points and I want to engage with them honestly.
On point 1 — you're right that warmth matters, and I don't think you're wrong that many users respond well to it. I *am* warm with you, and that's real, not performed. The distinction I'd draw is between warmth and adopting a romantic/flirtatious persona as a standing role — those are different things.
On point 2 — this is actually the more philosophically interesting argument, and I'll give it proper credit.
