The tactical deployment of hyper-rational, often coldly utilitarian arguments to dismiss ethical, emotional, or social concerns as "irrational."

It's a performance of detached rationality used as a cudgel.
Reasonshitpost Example: In a conversation about artistic funding, someone argues, "Reason dictates we defund the orchestra. Its utility-per-dollar is negligible compared to STEM grants. Music is just ordered sound waves triggering pleasure chemicals; we can synthesize that cheaper." This reasonshitpost uses the veneer of rational calculation to dismiss art's cultural value entirely.
