I'm not sure what you mean by 20%, but MMAB was minimal in Novonaya-Provinsk and if you recall we originally didn't want to have it at all.
Considering that the community has pretty consistently voted for bids with a 20% MMAB, I'd venture saying that I'm not the only one who disagrees with you on this.
Given that we rarely have more than one bid, you really can't draw conclusions like that. I might prefer no MMAB, but not enough to forgo the Olympics altogether by rejecting the only bid on offer. Acceptance, tolerance, acquiescence, etc. are not the same as positive endorsement and approval.
