Because it’s easy to be wrong. But besides that, in their own little echo chamber they think they are correct
There was a bloke on the radio yesterday having a go at the man in the hospital who was having a go at Johnson - this bloke ticked off every single false accusation I.e he was a plant, he had a microphone etc - it was explained how and why he was wrong. The bloke didn’t say ‘oh, sorry. And thanks for putting me right’. He hung up and probably still thinks he’s right today
It the good old days* if you were wrong and someone put you right you accepted it and moved on. Now people get labelled as a ‘liberal’ or accused of having some sort of hidden agenda. Strange times
