@manored,
Hi,
I think you make very good points and observations.
Something can just be different. Why must it be right or wrong?
I think there are very subtle reasons why humans adopt the notions of right and wrong.
Right and wrong denotes authority. That is, he/she who knows what is right and what is wrong assumes a higher level of authority - e.g. a judge, a teacher, a physician.
Whether or not there is a right or wrong, humans would like to believe there is one, so that they can have someone higher in the hierarchy tell them or guide them on what they do. There is a level of comfort abd security in such a notions (i.e. I'll just let someone else tell me or guide me), plus it off-loads a lot of self-work.
All this may be necessary in life, so what I do is accept it. I might feel that things aren't right or wrong, just different, but at the same time I accept that the notions of right and wrong exist and are part of the fabric of the human condition.
Does this make sense to you?
