You do not believe in objective truths. Yet you unwittingly participate in this behavior of doing not unto others. You came to believe in this through trial and error and making up your own mind using your subjectivity.
To you, there is no need for an objective truth. So now you're going to argue that there is no need for anybody to have objective morality as a guideline.
There is a missing premise in your argument. Do you see it? The missing premise is: everybody thinks exactly like you do.
Therefore if everyone thinks exactly like you, then objective morality is unnecessary.
But does everyone think exactly like you?
If there are two ways to arrive at one truth, whether people do it one way or the other is largely the result of the prevailing norms in our society's culture. If those norms were reversed, and less people believed in God/objective morality, people would still arrive at the same truth - subjectively.
What
is (the way the world currently is) should not be conflated with what
ought (the way the world ought to be). What you're doing here has been identified by Hume, as a logical error.
Just because societal culture believes X currently, does not mean that believing X is necessary (or ought) for the future. The fact its not necessary has been demonstrated by me, as an example, already.
