This country is very deeply divided. And it’s not democrat vs Republican. It’s not liberal vs conservative. It’s good vs evil.
My advice is to give him to God. Pray for him often...That God’s will be done in his life. Then concentrate on loving and caring for the child still at home. If the prodigal son ever comes back “home”, then welcome him with open arms. Until that day comes, live your life trying to do God’s will and leave everything concerning your son to God.
Bears repeating.
It is well to keep in mind "they" think "we" are the evil ones.
