No I'm not admitting that I'm wrong about pkg-autoremove(8) because there is nothing wrong with it, we have already proven conclusively that it works exactly the same as it does in other package managers. If there are problems they are in the ports system and how it organizes the inter-port dependencies. The bigger problem here however is that you're suffering from a nasty case of Dunner-Kruger effect and you're still hopelessly lost about what we are talking about.
