While its possible that Doc might be a gatekeeper... consider the alternative... activist mobs!
We face a future of politically driven activism similar to that which has the FCC censoring on the basis of "hundreds of complaints" which turn out to be from one source. This politically charged devisive form of astroturfing needs to be nipped in the bud.
I for one, think that a bit of careful gatekeeping might be in order!
Oh... the irony of it
