Trump looks like a cat who got the cream tonight, and the Queen has worked her charms on an "extremist" and made him nervous. For a man who doesn't care about protocol, he clearly looks to care deeply in his "moment" and not mess it up. Just shows what one can do when someone isn't shrieking all the time and can be adaptable.
As for policy, the biggest issue with Trump is he part of a recent change in politics that is eroding the recent norms and mindsets. I don't agree on Roe vs Wade, but when you consider that some states are deeply religious, it's not a large surprise to see it still be debated and things swing the other way. Democracies have to ebb and flow otherwise they become dictatorships, and at times things happen we don't agree with. It doesn't make one an extremist though.
