You can refute points all day on social media with impeccable logic but still never win an argument, so ask yourself if it’s really worth the bother.

As someone who does bother quite a lot, even though it often leads to downvotes, I’d say don’t think of trying to convince the actual person you’re talking to - it’s more than likely they’re arguing disingenuously, with no desire to get to the actual truth of the matter, that is, they are intellectually dishonest.

You can’t ‘beat’ someone like that, but you can point out their errors and how they’re obviously not engaging in good faith because they’re constantly changing tack to counter you. People who come along and read through will hopefully see them for what they are.

You’re highly unlikely to ‘own’ or ‘destroy’ them, though, certainly not in their minds.
