I see that dgib has already very effectively wasted your argument about abortion being a "constitutioal right", so I will gloss over that here, except to point out that your understanding of the actual Constitution and Bill of Rights appears to be lacking.
What I will address is court packing, which you also do not appear to understand. Trump absolutely did NOT engage in any court packing, none at all. What he did do was appoint three conservative justices to the Supreme Court, as he had a right and duty to do. Just because you do not personally like those justices, or approve of their judicial philosophy does not mean that he did anything wrong. Sorry to burst your bubble on that issue.
Court packing is is a term used to define enlarging the size of the court by ADDING justices that fit a different philosophy than the current makeup of the court, so that decisions can be counted on to lean to the side of the new appointees. In reality, with a current 6-3 "conservative leaning", doing court packing would entail appointing a minimum of 4 additional justices to the court to give it a 7-6 majority. I Harris is elected with a Senate D majority, you can expect a move to appoint 6 new justices, most of whom will be unable to define what a woman is and think that AR-15's can fire 6-800 rounds per second.
Here is the thing- what the Dems/libs wish to do is eliminate the concept of having 3 co-equal branches of government. They never want to lose a case in the SC, they want it to simply be a rubber stamp for them as they occupy the White House and control both legislative branches. And THAT, my friend, actually WOULD be the end of "our democracy"! Of course, you do understand that we do not actually have a democracy, right? Our country is a republic.
