It sounds as if your brother is not acquainted with science. DNA and gene expression account for most physical and mental health issues, along with social/environmental factors. And if we jail women for miscarriages, then the man should be sentenced right along with her as his sperm quality is just as much a factor in miscarriage. Let's get those jails ready, shall we? Maybe your brother could babysit all those kids whose parents are in prison...? Sorry this is happening to you, Lilith.
