Let me dumb this down for you, since that's the only way you're able to operate on here: when I (or anybody) make a comment about somebody without knowing anything about them, it's meaningless. For instance, if a random person who knew nothing about me said that my mom is whore, it would be nothing, since it's not coming from any sort of knowledge. If I make a comment about Herdman's daughter, it's nothing, as I don't know anything about her (she doesn't exist). If I make a comment about Raleigh's daughter(s), again, it means nothing since I know nothing about them (other than feeling bad for them since their dad is a piece of shit as a human). If I make a comment about Banker stealing childhood memories from his children, it means nothing, since I have no idea about anything regarding his children. If I make a comment about Walden's sister being hot, it's meaningless, since I know nothing about her (other than his comments that she is slutty).
My comments have no basis in fact/knowledge in them.
On the other hand, if I made negative comments about people who I do have knowledge of, it would be different.
