The thing is, to make an assertion of fabrication against other news channels is fine, however it's equally valid to make that assertion against GB News. If going down that route, one could argue they all fabricate to some extent to push their own agenda.just wasn't the place to say it on GB News due to the fact they are actually gaining a considerable viewing audience showing how fabricated other news channels actually are.
This is where these discussions become cyclical. e.g. an avid BBC News watcher might say 'BBC News tell nothing but truths whereas GB News promotes a load of biased guff.' Meanwhile the avid GB News watcher might say 'GB News tell nothing but truths whereas BBC News promotes a load of biased guff.'
Hence why it's surely healthy to obtain your world view from a variety of sources, even those you find 'wrong' to some degree.
