Kavanaugh "checks all the boxes" as a true-believer tea bagging Trumpster.
We could spend lot of time discussing his specific disqualifications for SCOTUS, but the most direct and succinct way of stating it is this: he knows for a fact that some relatively small percentage of people are just intrinsically betterthan "the herd" and he also knows for a fact that he is one of them. It is, therefore, his right and privilege---his moral obligation, actually---to instruct the rest of us about how we should live our lives.
He knows how we should worship God (atheism is not an option and God's name is "God" and nothing else), who we should love, how we should love them, which of us is obligated to obey the law and which is so important they can do as they damn well please, laws notwithstanding. He is, in short, a man surely selected by Providence to be one of the "chosen"---all conservative Republicans, of course--- whose duty it is to rule the rest of us.
If the above seems wordy and somewhat vague, let me reduce it down to the essentials: Kavanaugh is a privileged, arrogant, Ivy League white guy who is convinced his feces has no odor.
When Trump is impeached he and Gorsuch should also be impeached---or recalled or voided or fired, whatever; just so they go away.l
