Don't you guys think that at least one of those seven brothers would have preferred a groom to a bride?
I dunno... they got so much togetherness with the bros each winter. Maybe ANY woman was such an "exotic" entity that they could only fantasize about for too many months each year. That is why they were so eager to steal them. Also you could tell that all of the bro-bonding was getting on the nerves of Howard Keel/Adam and Russ Tamblyn/Gideon especially.
Now Snow White had an interesting situation. The seven dwarfs had to survive without any women and at least one, Grumpy, was more than happy not to have any around. Didn't trust 'em because of their evil wiles. Then again, he did soon "fall" for Snow White and she baked him a pie. Had the prince not kidnapped her and dragged her onto his horse, I think Grumpy would have fought the others to have full access.
One curio: the seven brothers and seven dwarfs required a woman to get them to wash up. In A Room With A View, the guys just stay naturally clean with all of their bro-bonding.
