I've said this many times, I've been arguing it for quite a while, and see a few people have agreed with this idea themselves on this forum. I know I wasn't the first who come up with it, but I did come up with it on my own, still don't want to acknowledge it but acknowledging it more and more everyday:
This was a debate with myself (X believes in morality, Me doesn't):
X:"Nazis were evil weren't they?"
Me:"I don't agree with the Nazis, nor do I like them but that doesn't mean they were evil."
X:"They killed thousands."
Me:"Why is killig evil?"
X:"Because it is morally wrong."
Me:"Says who?"
X:"Well, do you really want a guy coming into your house and killing you?"
Me:"No, but who says what I don't want and what I do want is the universal truth of what we should and shouldn't do?"
X:"Ninety-nine percent of people wouldn't want to get killed either, so it is wrong by law."
Me:"And yet, murderers are allowed to get killed without it being wrong?"
X:"Because they did something wrong..."
Me:"You're contradicting yourself. Why does the guy who wants to kill me get no say in wanting to kill me? I'm sure a majority of people would like to kill someone."
X:"Because the killer is not a majority."
Me:"So? As I said, I'm sure a vast majority of people have had murdering dreams or dreams to not go to work and get free money, why isn't that legal?"
X:"Because if nobody has jobs, there'd be no production and there'd be no electricity or anything."
Me:"So?"
X:"We'd all be suffering."
Me:"And?"
X:"That's bad"
Me:"Why?"
X:"There would be no happiness in the world if everyone could kill."
Me:"Why is happiness good?"
X:"Well, everyone wants to be happy, they want what they want, if they want pain it'll make them happy."
Me:"Okay? But because for the certain fact that people want different things and get happy for different things, it proves there can be happiness with anarchy or a world with no morality or ethics. All you'd gotta do is do what you want to do. If you want to smell good, take a shower. If you want to live, kill the murderer before he kills you, etc."
Couldn't think of anymore arguments further.
So... yeah, what determines killing, lying, stealing, etc. to be wrong? Unless there is a God saying "No killing!" there is only opinions on what is wrong and right, on what we ought to do.
And because they are opinions, why tell others what they ought to do?
