Sorry for the late answer! Anyway...
Aye. I've also found it funny when I read about some of the old rites in the neighbouring village of German here (the name is of Latin origin, btw, nothing to do with Germans) - when a hailstorm would appear, people would bring out their male babies, bare their butts and point them towards the sky, to chase away the hail (or something like that, it's been some years since I read it).
Exactly. The only reason "hordes" of "priests" started baptising the Russians was because they were allowed to do so by the authorities. The first conversion of the Rus, soon after the Bulgarian one (i.e. mid-to-late 9th c.), is a good example - it didn't face much support from the authorities and quickly went into obscurity. The same is true for practically every mass conversion in those times - no king to support you, no mass conversion (and even with a king supporting you, it still wasn't easy - look at the conversion of Norway).
Also, keep in mind there's a difference between an ordinary priest and a group of missionaries.
