Nothing is ever as good as it seems or as bad as it seems. This too shall pass. etc, etc...
I'd say let's at least, if we could, please agree that reasonable people can take different views on the items in your list. That there can be some middle ground on these things that don't necessarily make one side giddy and the other angry. That if we were sitting down with a couple of beers and just discussing some of these things that while we may not change anyone's mind, we might at least agree with some of the other's points of concern.
Can we agree that the supreme court has taken an outsized role in our society? That our other two branches have become unbalanced, with the executive taking too much power and the legislature too little, as the politics are easier to just let the administrative / regulatory apparatus govern without the need for those pesky on-the-record votes? Let the court decide, and then you can just shrug and say "well, I'm on your side!"
I don't know what will happen, of course, but I think it is reasonable to nominate and confirm a new justice before the next congress sits. I understand why that will be argued about quite forcefully, but I do think that this situation is a bit different than the situation at the end of Obama's term.
First, the president picks the nominee, the senate just confirms. The president is in a position of greater power to 'choose the candidates' as it were. In that case, we were guaranteed to have a new president, regardless of which party won. In this case, the same president is going to submit the nominee. Had Obama's nominee gone through the hearings, do you think the Republican senate would have confirmed him under those circumstances, or would it just have been a theater for political grandstanding with a forgone conclusion? An opportunity to get everyone even angrier?
Second, the justice in this case (Kennedy) is a middle of the spectrum judge. His replacement, even if it is someone who is to the right (probably) doesn't change every outcome. The last few days have shown that Kennedy already voted with the 'conservative' justices on many important cases. In contrast, when Scalia died, he was a staunch pillar of the conservative wing on the court. Had he been replaced with a liberal wing justice, that would have changed many more potential outcomes. It would have been a much more dramatic shift of the court. It would be more like the scenario of Ruth Bader Ginsberg retiring and being replaced with a conservative justice.
That scenario will happen soon enough, I imagine. God help us when it does, given the state of discourse in this country.
