How to fight LLM-based thinking?

I've had multiple discussions with people, typical western liberals, where they heavily relied on Chat GPT for their arguments and information.

I was explaining my perspective on Iran to someone who said they support a regime change operation there by the US. I told them about how the protests started peacefully, until a sudden coordinated mob created destruction and violence, and how the riots ended after the starlink tech was shut down by the Iranian government.

They told me my argument doesn't hold water because they GPT'd it and it said everything I said was wrong. Is it just a lost cause to try and explain further at that point, or is there a way to break people away from LLM-ism?
