I would invite them to put their money where their mouths are and unenroll little Johnny. You send your kids to Catholic school they will get a Catholic education and that includes the church teacings on homosexual acts and divorce. Perhaps they would prefer to send their kids to one of the pro-sodomy, pro-divorce public schools.
Their kids can also get the crap kicked out of them by the feral thugs that run wild at the pro-sodomy, pro-divorce public school.
If they don’t like Catholic teaching they need to go somewhere else.
Yep. Any appearance of compromise is a bad idea.
