The problem with arguing on the internet is that you usually automatically assume that the other person is as cognitively capable as you of understanding the argument you’re trying to put across, and also, are interested in the argument at all.

Often people cannot understand something - perhaps they are lacking critical thinking skills or literacy, or perhaps they are genuinely mentally ill - or maybe they simply don’t WANT to, and are using the argument as just a way of letting out the frustration of their day.

They are not open to accepting other peoples views or genuinely challenging their own position, they just want to forcefully re-iterate what they previously believe, often to ’let off steam'.

No amount of keyboard bashing on your part, is going to change these things.
