Serious statement: I don't understand the argument that not voting for Harris was the morally correct thing to do, because of Gaza. Why does anyone believe this?

1. the world doesn't owe you at least one morally correct choice. They can also just all be morally bad choices. (hello classical greek drama btw)
2. morals depend on your point of view what correct behavior is and on the social group you want to be respected and accepted by.
3. because of that, morals are subjective, made up, and can be whatever anyone wants.

So xyz being "morally correct" and saying that, is just that person's point of view, and if you have a different point of view, it's just a difference of opinion.
