Not angry, just wondering if you had checked out your Shop Manual. The page you gave might not have helped you get the front hubs off.
Most likely, you found this explanation for the front drum/hub? It is not uncommon for the rear drums to be difficult to remove. Be sure you have first backed-off the shoes quite a bit. After you have removed the retaining nuts (if they are there), you might then have to pry or pull the drum, or lightly hammer the drum from the rear, in order to break the "rust weld" of the rear drum to the rear axle hub.
