If that's the only meaning you see in life then that's kind of limiting, don't you think? So anyone who doesn't personally have children is wasting their lives? That seems like an awful lot of people, a lot of whom aren't homosexual or any other label on your list of unnatural nasties.
I did limit my description to simplified path for meaning of life, ignoring side stories.
If you focus on any living organs from germs to trees and plants, from fish to human beings, their meaning of life is to born, to survive, to eat, to spread and to die.
Also to comment your last sentence. If man wants to go surgery and attach rubber boot his forehead. Nature has not meant rubber boot attached onto his head but if he has money and strong will for surgeon to demand this is they way he identified himself as rubber boot man - fine. Surgeon would do best to attach rubber boot on his head and make customer happy.
I still would call this man an idiot. Same definition goes on surgery and hormone changed transgender people.
I think your basic atheist philosophy is a lot like my alpha male cousin Karl, whom I respect and admire. He enjoys a good laugh.
So I'd like to ask what you think, briefly, the phenomenon of consciousness is basically all about. Is it exclusive to humans, or does the ant partake in it? What do you make of panpsychism or animism as religions?
Cheers. I don't consider me being alpha male, but I keep my own opinions and don't follow the flow. This doesn't seem to be acceptable on some people and I hurt their feelings though no intentions on it.
What comes on consciousness, I'm sure every living organ has it. Some more basic, some more developed. Did you for example know when you are lawn mowing (cutting the grass), maimed grass and hay will begun to spread chemical toxins around "to make it stop and alarm fellow grass"?
It doesn't effect on lawn mowing person at all but smell of cut grass. But that is all what basic grass as defence can do.
So lawn mowing is murder!
So my vote goes on panpsychism. As an atheist, I don't believe in souls, gods and I think every religion as basic are wrong. Religion is human defect like transgender people.
