I've known girls to stand up and say NO to a proposal which the whole family is CRAZY ABOUT except the girl herself. They just stood their ground. And the parents understood that it could be a potentially embarrassing situation to put forth a stubborn minded girl in front of the guy and his parents. Cuz who knows how she might behave with them and thus embarrass her family? The parents didn't want to take that risk, so the daughters weren't pushed. Plus, the parents, upset as they were, respected their daughters' wishes and sincerely loved them.....that's why the dropped the issue when they saw it was pointless....rather than emotionally blackmailing/forcing, what have you.
The parents who do force are going against Islamic principles and are treating their daughters like cattle.
