Is it the 4th Commandment that requires us to honor our father and our mother?
What would you have a son do who loves his father even though the father is a flawed human being like the rest of us?
Exactly.
And what does it matter whether his father is a communist, a Nazi, or a Quaker?
Good grief, if someone attacked my parents, on national TV, the last thing I would do is agree with them. No matter what I thought of the privately.
