Again I agree with you - unfortunately!
Nevertheless, it's been shown that societies work best when there is some degree of support and respect for others. Of course, that means that the "top dogs" miss out on some of their bones, so it seems that they're deliberately manipulating people to act tribally.
In fact, if you do have time to attempt Cummings' blog, you'll see that's precisely what he's trying to do. The man seems utterly amoral. For him, winning is all that matters and he couldn't care less what damage he does. It's actually ironic that he's now accusing the Conservative Party of not caring about the NHS and the poor, etc - I wonder what he's up to now. It all reminds me of the historical revolutions, with factions all fighting each other and jostling for top spot. Of course, they need to claim the alleged "will of the people" to legitimise their actions.
