Why are democracy and politics such an overwhelming shit-show? Do you want to know? Really? Here, let me tell you why - in one brief summary:
The dichotomy of left vs right in politics itself lies at the very root of the mess. It is in itself a major flaw in modern democracies, because this instantly and irrevocably sets up issues like basic human rights at the center of a perpetual maelstrom, placing human rights and dignity up for grabs for whichever side wins any subsequent elections - and that's precisely why nations like the USA rarely make any substantial or lasting progress on human rights issues, because their entire political system is set up around fighting either for or against who is allowed or supposed to have equality, and the opinions of those who oppose them having those rights or equalities.
