sure it is, can you tell me a subjective moral that isnt based on an opinion?
Morals
are opinions. You originally said “only”, which you conveniently removed.
Take the idea “stealing is wrong”: at the individual level, it’s based on empathy, which isn’t opinion in the sense that we can decide to think something differently; empathy is ingrained in us.
At the societal level, it’s based on benefit: if we work together, each of us will be able to acheive and get more of what we value. If we steal from each other, then we would ruin the mutual trust that allows our society to function, and as a consequence, we would lose the benefits of society.
then why shouldnt a person perform any act that they want?
Because we have individual senses of right and wrong.
Because we have to work within societies that, for practical reasons, must have shared codes of behaviour. This doesn’t mean that these codes are set in stone, but it means that we have to take them into account if we want to be members of society.
Homosexuality is a single moral principal that’s true in all circumstances, is not natural, regardless if there is a creator or not.
The fact that homosexuality occurs naturally would seem to contradict your assertion.
Also, I’m not sure how whether something occurring naturally or not factors into morality. If something’s unnatural, then it’s just impossible. I don’t see how that implies immorality. I mean, it wouldn’t be “natural” for me to fly by flapping my arms, but if I managed to figure out a way to do it, would I be acting
immorally? I don’t think so.
The existence of the human race requires sperm and egg, not sperm and sperm, not egg and egg, therefore those who object to the natural law for the gratification of self imply a disregard and destruction of the race, which is objectively immoral.
If failure to have offspring onesself is immoral, then bees are the reprobates of the animal kingdom.
