In a Discord conversation, I say I've just come across a bizzare blog post, then in a single message I share a link, paraphrase something bizzare as a question, & follow it up with "What the hell are you talking about?"

Now, in that context, it's obvious that "you" refers to the blogger. It's obvious that "what the hell are you talking about" is a verbalisation of my reaction to the blog post.

Anyone who interprets "you" to mean the person I'm talking to on Discord is being obtuse.
