I briefly got caught up in such debates during the worst of the pandemic, and it was fruitless and a total waste of my time.
Every time the person asked for something to prove they were wrong, I'd show them. And they'd never admit it and go onto another talking point, and I'd disprove that. Rinse and repeat a number of times before I finally called them out on it and just walked away from the conversation.
Save your time and energy for something positive instead.
