Nobody should tell anyone what bike they should start on. If you want to start on a 1k and can afford it, go for it. Know the risks involved and good luck to you. If you wreck, you wreck, if you learn, you learn, who cares, I'm not the one paying. You get into motorcycling because you've been dreaming of that one bike, why restrict yourself for many years on something small and different? Be happy with whats sitting in your garage, don't dread riding it. Some people don't like 250-300's styling, sound, and power so I understand on beginners starting on something larger. Of course I also recommend starting out on a smaller bike, but I'm not here bashing 1st time riders on 600's or acting like starting on anything bigger than 300cc is the worst idea in the world AS long as the person riding the bike is having fun, thats all that matters regardless of skill level or riding capabilities
