You didn't. That particular comment wasn't directed at you specifically. It was a general observation. However, I understand why you might think that it was directed at you. Apologies.
Nevertheless, my point stands: This is a non-story. GB News are considering the future of one of their programmes ... And? It's no surprise that an organisation should review the performance of one of its' products.
Yes, it would be a strange behaviour to complain about a TV programme which the person has not seen. However, it is an assumption that is the case. In any event, why assume that such behaviour is limited to lefties? It's no less (or more) likely that right-wingers who don't watch HIGNFY might complain about it.
