Have you given birth or raised children? I have. There's a big difference between embryos and fully formed babies. 40-60% of blastocysts don't make it through the implantation phase of pregnancy. Do you believe in a higher power? If so, she is the biggest abortionist of all, right? That's nature, and I don't worry about how many embryos dissolved in my or anyone else's uterus. It's none of my business nor yours either -
