the whole left-wing thinking wins by default in any kind of moral debate. Because they accept everything. Literally everything about acceptance is okay, there's no middle ground, it's just do whatever you want, be whatever you want. It's hard to debate against someone using textbook lefty inclusiveness, because you look like an asshole not wanting someone to be "happy". But the problem is that inclusiveness and brownie points eventually collide and then the left eats itself viciously
Example: islam and women's rights. or minorityA and minorityB competing for who has it worse.
My problem with the way the left "thinkers" handle stuff is that it's rarely productive. If we followed that path society would simply endlessly spin in circles not being able to make any concessions for a mutual understanding. Don't get me wrong, the right and it's extreme version suck balls too.
