You stated it was egotistical to believe in and express absolute moral standards, didn't you?
In that, I think I detected some disapproval on your part...
You indicated that egotism was wrong...
...Which is very interesting when you consider that you claim to be fully capable of being able to self determine your own moral standards.
Being self-deterministic morally is to be egotistical.
So with that thought, is egotism wrong?
Since you seem to be confusing correct/incorrect with morally right/morally wrong, I'll make it simple for you:
Pretend that morality is like ice cream. You are saying that there is an absolute best flavor, and I am saying that the best flavor depends on the person.
By saying there is one flavor that is the best, and that you know what tastes best, you are saying that you know what the best flavor is. Since I am saying that it depends on the person, there cannot be a "best flavor". This is why I mentioned that your position is egotistical; it implies that you know what is right/best and other people do not. If it is subjective, I am free to believe that my favorite flavor is the best, and I understand that you may have a different favorite flavor.
