Of *course* it's our place to make subjective
editorial decisions on
whether or not content is appropriate - where appropriate is a
broadly-defined mixture of "acceptable", "useful",
"well-placed", etc
etc. We do it all the time, as a community and as individuals or
ad-hoc groups. There's no 'Big Book of Encyclopedic Merit' we refer
back to...
We don't use those measures to decide, though. We use verifiability
(which is pretty objective) and notability (which is not, but appears
to be pretty much unavoidable if we want to be realistic). Censorship
is clearly subjective and avoidable, so should be avoided.
