My "actual interest" is to have a conversation with you about Objectivism. I want to hear your arguments about why I'm wrong about Objectivism, not the arguments of the person who made the video you sent me. If I wanted to argue against the person who made the video, I'd seek out that person and proposition them to debate, but I didn't. I commented under *your* post, which any rational person could easily tell means I want to hear what *you* have to say.
