I see no difference in Cristiano Ronaldo and a porn star and an influencer and whatever you name it. They are all idols that sell stories for people to project their own thoughts and desires onto and get emotional. I would be more worry about my kid believing in celebrities, regardless of who they are. And the American mainstream culture is filthy anyway. As the old French joke once said the difference of yogurt and the us is that if you leave yogurt for a coupled of hundred years they would develop culture.
