"Changing the subject during an argument, often a logical fallacy called a Red Herring, is a deflection tactic to avoid the real issue, often because someone feels they're losing, is tired, feels attacked (ad hominem), or simply lacks knowledge. While it can be a defense mechanism to de-escalate, in a healthy discussion, it often signals evasion or a desire to control the narrative, requiring you to gently redirect back to the core topic."

That's what AI says.
