Halacha of Adultery: Proof that Yahweh was Immoral Had He Existed (which of course he did not)

A married man can have sex with a woman (so long as she's not married/property of another man and so long as he doesn't rape her) but he cannot eat chicken with milk or turn on a light switch on Shabbos? Or wear shatnez?

Now, if this isn't a litmus test for how morality has shifted (Shifting Moral Zeitgeist) for the better since the writing of the Torah, what is? (feel free to submit as many absurdities as you like).

Meanwhile, a woman who is married is prohibited from adultery and is killed for it. Whereas, if a man rapes an unmarried girl, his penalty is to marry her! Moreover, the torah spells out the elaborate (and Wizard of Oz-like) Sotah ritual in great dirt-eating detail, while no such test of a man's character exists.

To add insult to injury, chazzal decided to use the Sotah ritual to further knock women down. It is the sole "source" for a woman's "obligation" to cover her hair (usually with a sheitel/wig which looks like a dead cat). This absurdity is one that orthodox women live with to this day, public submission that ensures that at least a part of the Sotah humiliation will live on.

The above fact are well-known aspects of halacha, however unspoken. They are PROOF- yes
P-R-O-O-F to those that believe in Yahweh, that was totally immoral by today's standards.
