As far as psychology -what is notmal?

Scientifically? There is no such thing as "normal", not as you or I would perceive it from a belief standpoint. "Normal" is just the mean and median of the data points, graphed along a bell curve.

Is it not what is predominantly observed in society, that incorporated historically and culturally -objectively when looking at arbitrary things, that which is not self destructive?

No, not really. I mean, it used to be "normal" for Catholics to force Protestants to convert at sword point, and on failing to do so, burning them alive at the stake for heresy. I wouldn't call that not self-destructive. But it was certainly for the time.

Homosexual sex is abnormal AND self destructive individually and societally

From a belief, religious, and cultural standpoint, I don't disagree. I would disagree that it has been proven beyond all reasonable doubt from a scientific and mathematical viewpoint - which is what wins you court cases.

YES REALLY -you stated as much yourself: "Normal" is just the mean and median of the data points, graphed along a bell curve." Normal people do not express love by engaging in self destructive intrinsically disordered activity...
