Why should it?
If you do not like a bike, just move on. No one says you have to like every bike here. Just ask how close does the chain come to the tire - just ask, because you cannot know.
As for things about the derailleur, you have no idea relative to what conditions he rides. I have clipped my derailleur on my 24" and 26" and 700 wheels, because there is always something big enough to hit it, somewhere.
