At what point can you look at a group and claim that they accept or even "like" something? For example, how many hockey fans have to accept or like fighting for us to say "hockey fans accept fighting as part of the sport"...50%...60%? When I see 15,000 stand and cheer a fight at a hockey game, I would be comfortable saying that "hockey fans accept or even like fighting in the game.
In the case of Islam, when you see stats that show high 80% or even 90% acceptance of certain ideas, I'd say that a high enough number of Muslim acceptance of stoning, hatred of homos, rape, misogyny, FGM, hatred of western beliefs etc. that I can comfortably claim that "muslims have a stone age backward philosophy".
