Wow, it takes a particularly arrogant flavor of chutzpah to declare that laws given by God are "silly and evil."
Those laws were given for a particular people in a particular time. Their culture didn't have any Constitution, Bill of Rights or judicial system with trial by a jury of peers. To judge their law from your perspective of comparative pampered ignorance is the very definition of foolishness.
Do yourself a favor and stay far away from Biblical critiques.
Then don;t support the idea that these laws should be applied in the here-and-now.
Of course, there's also the little fact that the OT *and* Jesus declared that those laws would apply forever, so using the "particular people in a particular time" arguement doesn't work either.
