A druggist doesn't have a fill a birth control prescription if he thinks it is immoral. An employer doesn't have to provide insurance coverage for birth control pills for his employees if he thinks it is immoral. A Conscientious Objector doesn't have to go to war if he thinks killing is immoral. I bet there are other law like that.
BUT if you think bulding a wall at a border keeping people out is IMMORAL you are out of luck.
Who dictates morality? Who has the final say on exactly what constitutes immoralilty? A prez? A judge? Or the person who believes it? Do you let others DECIDE FOR YOU what ir moral and what is not?
