Patur Aval Assur,
It seems that the answer to everything is that intellectually speaking it doesn’t make sense, but you just feel it (which I’ll admit, I do).
What do you mean by intellectually?
I would say:
It seems that the answer to everything is that animalistically speaking it doesn’t make sense, but humans innately perceive it.
But that means that if someone doesn’t feel it, or if he has other feelings drawing him in the opposite direction, there shouldn’t be anything wrong with that.
If humans were just another animal, I would agree with you. But we’re not.
But why is there something wrong with not having the proper feeling.
Using your definition of “intellectually” above, can you intellectually define any behavior as wrong?
