People have, and are shifting to a worldview that doesn't rely on moral truths existing anymore, it instead relies on facts and evidence. All things that don't have it, get disregarded and thrown away. A great time to live. Truly, a great time to live. Moral truths, something that has zero evidence or reason to be considered true in the first place, finally ends up back in it's proper place. Funnily enough, I got into a very long and drawn out debate with a bunch of vegans on the topic recently. The only real "debate" is the same as the same debate that comes up when you debate anything spiritual "well, nothing says this is true, and we have zero evidence of it, you can't really disprove it with any amount of evidence, but guys, it's possible!" It isn't good enough for me, and it shouldn't have ever been good enough for anyone. Yeah, there is a debate, but it's long gone and long settled. Pointless as debating if the world is flat.To me that just confirms that something has gone awry in our culture - people are not merely siding with moral antirealism and relativism (which could be fine), but they're not even aware that there's a debate to be had about this and if anyone proposes a debate they get written off as an idiot.
