Yes, as an aspiration, I think it would be fine, and I think to distinguish between what is verifiably factual and what is personal opinion would be -- is a reasonable aspiration.
However, I'm aware that in most newspapers and elsewhere in the media, that is in practice quite difficult to maintain. It is quite difficult in papers -- say, for example, the New York Times, which does aspire, like many American newspapers, to separate the two. One can often find the bias of the newspaperman or of the commentator quite strongly there. It is quite difficult to do, but I think as an aspiration, it is a reasonable one.
