When you start having political discussions with your kids you try hard to give them the facts, hope you have taught them to be critical thinkers and then let them make up their own minds. The best you can do at this point is mentor without preaching and guide without leading. Parsing some topics though is a tough process, for instance this one quote which hits on more than a few key topics… 
“I’ve struggled with it myself for a long time, but I came to realize that life is that gift from God. And even when life begins in that horrible situation of rape, that it is something that God intended to happen,”
