No, you did not. You have made such false claims as 'If you can't get there without a stop at Mars, then you really, really can't get there with a stop at Mars.' This is a claim that is easily shown to be false by calculating the differences in delta v from Mars to belt/outer planet destinations vs from Earth. You then claimed what you meant was that it takes more energy - but so what? It takes more energy to refuel in LEO than it does to launch a ship from the Earth surface to escape. Basically this entire time you have simply just claimed 'no, you're wrong' without any calculation to back it up, and the few claims that you have made have been ludicrously wrong.
