The problem is that this Jackass has been appointed for LIFE! Something is very wrong here and we will eventually have to face up to it. The Supreme Court is a totally dysfunctional governmental body that requires repair. Getting Scalia and Thomas off of it quickly would make a lot of sense. We have been dealt a bad hand by our Constitution and need to straighten that out! There really is no more point in individual complaints against these Justices. They need to be removed. Why we have no effective mechanism in the Constitution for doing that is beyond me. These men act like God appointed them to be our Gods.
The idea of appointment for life is that it prevents Supreme Court Justices from being sacked for political reasons. Would you prefer a system where the G W Bush administration would have been able to fire the entire bench, and appoint nine new justices of their choosing? Or where the House Majority Leader could lean on the justices to rule the way he prefers, under threat of replacement by someone more compliant?
With life appointments, nobody can fire someone just for disagreeing with them; and in principle one or two bad apples can be voted down by their more rational peers.
Life tenure tends to limit the number of new appointments per President to one or two, so that it would take a
very long period of consistent voting in of Presidents of one political position to stack the SCOTUS in favour of one viewpoint. And once appointed, justices are beholden to nobody to keep their job, so the influence that the President (or party) that selected them has is much reduced. This makes it very hard for even a fairly long period of voter-backed extremism to be reflected in the make up of the bench, and so has a moderating effect.
A lot of the best provisions in national constitutions (including, but not limited to, that of the USA) are the ones that make it hard to get things done. This is a feature, not a bug - if ideas are only popular for a few decades, they tend not to get imposed on the people. Only the truly long-term social changes end up reflected in law, and if an idea can stand the test of time, it's often worth waiting for, if only to filter out the ideas that sound good at the outset, but which turn out to be dangerous fads.
