Facts do matter. However, that wasn't what I was asking. You both believe you understand the facts GSM and WWM2. Yet, from what we read, you are likely to vote for two different parties with contrasting and irreconcilable views. This can only be because your perspectives and those are based on your feelings, not facts.
Many people will vote on those feelings alone. However much you could try to beat people up on GN for not using your preferred facts, it will not change their feelings about what is right and what is wrong from their personal perspective. They each have the same number of votes as you do - 1. Many people will vote in the next election simply by using their feelings about whether the last 13 Tory years have left them better or worse off. That makes "feelings" important, possibly as important or more important, in an election as facts are.
Not sure how you glean that from my very short post to gsm
