I did see the episode of QT and believe Fox was unfairly criticised and that it’s unfair to use it to reinforce the current argument.
I think a lot of people (me included) do see it as relevant though, which is why it is being taken together with the GB News thing. It doesn't make the comments worse, but it does give a fuller picture of how loathsome the man is, and shows that this is not an isolated example of his behaviour. There are many more, including his drunkenly burning Pride flags and posting it on YouTube.
He is clearly 'not at peace with the world', and probably needs help. I'm not sure that giving him a public platform is good for him, really, but as it's hard to argue against that in the interests of free speech, he has to take the consequences of his rants.
