The Importance of Public Grave Sins

Some people say firing a pregnant unmarried teacher punishes her for not getting an abortion. So what about teachers in invalid marriages or ones who use contraception? Well, if they make these sins public to their students and say that they aren't a big deal, they should be treated like LGBT teachers did with sodomy. People who engage in public grave sins are unfit to be Catholic school teachers because they scandalize students and undermine church teaching.
