"Overheated" and "chilled" aren't antonyms here, at least not in the sense I think you're using them.

Overheated: the discourse has too much anger or vitriol, or is too personal and emotionally charged.

Chilled: people have given up on discoursing at all.

If this is what you mean, I don't think we want less discourse as a solution to bad discourse. We want to maintain but temper the discourse.
