I think it's more a matter of childish mine-is-better bragging by DSLR
advocates who feel the need to feed their egos by putting down non-DSLRs
and those who use them, like wearing a Rolex to be more cool, or worse a
fake Rolex, like cheaping out with a Sigma or Tamron lens on a Canon or
Nikon body.

it's just as childish to do the reverse, putting down dslrs and in
particular, third party lenses, some of which are quite good (not all,
of course).
