As far as I'm concerned there can be political programming from any ideological viewpoint. People should be able to put their views out there and have them robustly challenged.
My gripe with GB News is that is it's not a news channel, has designed itself to get round meeting the requirements of a news channel, but then in many ways markets itself as a news channel. It does so because it taps into the political disillusioned element of British society and the people who feel a desperate need to feel someone's on their side against 'the establishment'.
What these viewers fail to realise is that GB News is the establishment. It's just doing what a certain group of UKIPpers, right wing of the conservative party and hard line brexiteers have been doing for years: aiming to move the overton window to advance their interests.
In my experience you get a handful of people who'll, quite rationally, say that GB News isn't a news channel but they've found some perspectives on certain issues interesting, but they are a minority.
What you get far more of is people saying GB News is news, just the woke, left wing sheeple can't handle the truth, there's a huge media conspiracy against the talking heads on GB News, something something BBC, Guardian etc. It would be interesting to see how many other conspiracy theories people like that cling to.
Most people I know across the political spectrum don't regard GB News as news.
