I think this is much sadder than just the parents thinking like this. Kids should get to be kids and start their lives unencumbered by their parents' hatred and bitterness.
Unfortunately kids are born with all the sins our world already bares. We can wish and hope for them to be free of the. But that is not reality. No matter what what's happening is happening and will affect them. We must be better about giving them that world actively and preparing them as needed to be adults in this world.
Had some people in a duel enrollment (collage level) class tell me last Friday that they'd vote for trump because "he's an asshole but I like his policies"
