i see theres actually discourse on this. Lemme lay it out then.

Yes your all right AC use can be mitigated by proper building techniques. it does cause lots of emissions. its also necessary for many people and places regardless. Its also way over used in western society.

None of that matters. The specifics of when to use or not use AC arent relevant right now because under capitalism your never gonna get houses built better en masse, and the only thing thats gonna be considered is how can we build houses even cheaper to make more profit and sell more AC units?

This is a discussion we can have all day and its never gonna matter.

The only thing worth discussing here is the fact that currently the powers that be want to sell you a home that needs AC and has AC and then shame you for using the damn thing.
