Explain the actual harm. Enumerate it. I get that you don’t personally like it, and thus don’t want your child to watch it, but do you think it’s going to make your child a rapist?
Many people have presented their case on this issue. In this thread or elsewhere. Please don't pretend they don't exist by saying "Explain the actual harm. Enumerate it." Where's your proof that these videos are harmless or even beneficial to children?
I'm sorry, but this is not just "Other commentators agreeing with you". Those arguments are, in fact, sufficient for me to believe that these videos are harmful to children.
