Brilliant! I love a bit of trolling....
It's a crop factor because the sensor is smaller than the lens mount was designed for. The field of view hasn't changed, you're just not recording all of it. Yes, it's a design limitation, but also indicative of the fact that people start off in photography wanting to go longer. Only after a series of disapointing shots do they realise that going long doesn't make for good pictures.
Anyway; conversely, people don't like being told that if they won't spend $500 on a lens then they're in the wrong hobby... what kind of elitist nonsense is that? I bought an SLR (film) with a 50 f/2 lens for $5. If you can't make nice pictures with minimal equipment, THEN you're in the wrong hobby!
Ok, the guy wants the moon on a stick (a fast 50 with the FoV of a 30mm) when really, you'd be better off just walking further away from what he's shooting... still, no need to insult the guy, even if his end result will be somewhat lomographic.
Jeans: if you're going to perform sex acts for money, at least make sure you get the money up front!
