Therefore, you would favor preventing people who've had abortions from working with children (that eliminates about 25% of the female population)? Let's also prevent people who used to smoke pot from working with children (that eliminates some 60% of the population). Let's also prevent people who've cheated on their taxes, told a lie, committed adultery and stolen something in the past from working in cafeterias where our children eat.
Wow! The only people left are you and me. I've got a job, so good luck serving all those meals....
