I think he has reached a point in his career when he can afford to say — I don’t care.
His place as the Oscar host has been replaced by two gays (consecutively).
Ellen Degeneres last year and Neil Patrick Harris this year.
He’s probably old enough to see the effects of such hypersexualized programming (twerking, flaming homosexual subplots, etc) on his grandkids/nieces/nephews. Maybe he’s even observed some inappropriate activity between adults and minors on Hollywood soundstages.
