Based on his writings/interviews it appears that the late Justice Scalia was most concerned about an unconstrained court imposing its version of utopia upon the citizenry. If PEtD picks justices who follow that mantra, we'll be ok. The quest for a more perfect union will devolve to the legislatures and the voters.
Will the legislatures and the voters get it right 100% of the time? Nope, but part of our checks and balances will be the executives and judiciary to reign in the wilder impulses of the people.
The justices need to curb their wilder impulses, too. Just because RBG or CT is personally offended by a case brought before the SCOTUS, doesn't make the plaintiff or defendant's argument wrong. Our justices' check is what is written in the Constitution.
Being a black and white type of guy, I don't like penumbras. Maybe should not cut it.
Call me Capraesque? Yeah, I'll probably agree with you.
Bash away. That's what you do best, anyway.
