These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Alternative Character Interpretation: Some theorize that the "crime" is not homosexuality, but emasculation. Others point out that the wording in the verse certainly refers to sexual acts, with some contention on the subject of which sexual acts are referred to.
Big Lipped Alligator Moment: The "Zipporah at the inn" episode. After God sent Moses in Egypt to deal with the Pharaon, HE sends his angel to kill His prophet for unexplained reasons. Then Moses' wife Zipporah takes a sharp stone, and cut off the foreskin of their son. This apparently saves Moses. It's pretty obscure and no wonder why this is often ignored.
Values Dissonance: Yes, there are laws about how to deal with slaves. These would almost be hilarious (if not for the slavery), considering they're given to escaped slaves. There are also laws saying that the penalty for rape is marrying the victim and paying her father 50 shekels. And if a woman wasn't a virgin when you married, or has been unfaithful, you can have her executed.
Fair for Its Day: Said laws did give slaves of the Hebrews much better lives. Fellow Hebrews who were slaves were expected to be freed after 6 years of work and generously paid at that time. Foreigners could be slaves for life but if they experienced violence at the hands of their masters they were automatically declared free under the law and a master who killed their slave/s would (under some circumstances) be charged with murder. Slavery in that context was quite different from the slavery in Egypt or the slavery in America before the Civil War and closer to indentured servitude.
However, the master is not guilty if the slave dies three days after he hit him...
And while the rape laws are definitely unfair to actual rape victims, they also apply in the case of an unwed couple having consensual sex. One wonders how many girls used this to override any parental objections to marrying their sweethearts. "Oh, Daddy, I know you don't like Yaakov, but he ravished me last night, and now the law says we HAVE to get married!" Also, Deuteronomy 22:25-27 mentions that the punishment for a man raping a woman who is betrothed to another man is death and that their victim is innocent.
Leviticus 19:19, however, which commands us not to wear clothing made of two different kinds of material, is often held up as the Up to Eleven of absurd religious commandments.
Some point out that following the above command is easy and harmless.
The later, more terrible plagues are justified by Pharoah not taking the hint from the earlier ones. The problem is that God explicitly had to intervene to "harden Pharoah's heart" and keep him from giving in too soon. Doing such to promote his own glory was perfectly acceptable to the books authors, but is straight-up God Is Evil to many modern readers.
Though some state that God "hardening Pharaoh's heart" was merely restoring his fortitude after Pharaoh had been shaken up by what he'd seen. Then Pharaoh took that fortitude and used to continue disregarding God, bringing further trouble upon himself.
