Nobody's demanding unanimous thought, but we've had a spat of bad-faith detractors over the last few decades that use that same argument to justify a lot of attention and time to batshit crazy things. We demand unanimous collective thought in plenty of places, deciding on where to do for dinner, juries, we should all drive between the lines and stop at stop lights, etc. But taken even the hall, they kept Piazza out for years because one batshit crazy blogger mouthed off about bacne and enough people gave that attention. Sometimes the .3% is the guy that decides the stop sign is optional, and we shouldn't applaud his not falling into groupthink or whatever. Also the BBWAA voted to make ballots public, it's the Hall itself that's the holdup.
