I don’t think it will change any minds. What he is doing is actually unethical in his profession. None of the people involved are his patient, and he has a personal connection that would prevent him from being able to take them as patients. He is a biased observer who is defending his father.
No one legitimate would try the “doesn’t fit the profile” gambit, anyways.
For me, I made up my mind due simply to him having sexual relations with his own stepdaughter. And it wasn’t like he broke up with the mom and then later fell for the daughter. He was just that immoral to do such a thing.
That fact is enough for me to accept that he’s a sexual predator. And I’m someone who still is unsure about Michael Jackson being a sexual predator.
