Sorry, I should have prefaced this with the idea of rightness and wrongness within the scope of what is legal. Of course, we as a society have the right to make a law that defines the spraypainter as wrong, but we've left it up to the individual's conscience to stand outside my home in the street, with a picket sign proclaiming his hate for kittens. Repeated such behavior can allow me to avail the law to get a restraining order, if I can show possible harm, but that's my option.
Within the law, people have to make their own determinations of what is right and wrong for them, using their own intellect, education, and experience. I reject the idea that everyone needs some preacher interpreting some ancient book in order to know what is right and wrong.
2. So, anything goes in your worldview, all is relative. You would have no problem if someone came to your house and killed your goldfish.
Ugh, another reference to trespassing, and the destruction of another's property, all of which are fully covered by the law, based on ethical principles of treating others as reasonable persons like to be treated. However, if you want to buy goldfish, and kill them, that's your right under the law, and no matter how much of a goldfish-hugger I am, I don't have the right to do anything but decry your behavior, write books about it, and give interviews where I call you a goldfish murderer. I even have the right to ask my legislators to pass laws protecting goldfish, and they have the right to laugh in my face, if they see fit.
Can you come to moral absolutes without using the opinions of people?
You seem to have a powerful need to have moral absolutes, and be able to stick them on others. Feel free, enjoy being told what to think, and telling others what to think, as well. It's impossible for me to reason with anyone who has a worldview such as your own.
Funny you should bring this up... it just so happens, that in Germany around 1940 or so the government decided it was legal to round up jews, imprison them, use them as slave labor, use them for medical experimentation, gas them, burn them, and even to skin those who had tattoos in order to make lamp shades. Now then, if it so happens that at some point in the future it becomes legal to do all of this to you and yours it would be fine, right? Just so long as the people doing this to you have used their own intellect, education, and experience to decide it is right, and what kind of wood to make the soap bars from, eh?
If you reject the idea that you need some preacher to tell you what some book says that's fine. Ever hear of some guy named Martin Luther? Why don't YOU use your own intellect, education, and experience to read it? Heck, why don't you set out to prove it is all hogwash just like Simon Greenleaf? (psst - you may want to study up on this guy before you launch into that one, though)
