50%?!!! so you think all of our women want to go to stadiums? language in our stadiums is so dirty that families can't attend them (even if it was free). do you think all of our women want their husband and kids to enjoy a full view when they watch a match?! all families want the behaviors in the stadiums to become a norm and model for their children?!
point isn't the law but culture, the culture which almost everyone wants to preserve.
once during Ahmadinejad era, women were allowed in stadiums, and the result was that they decided to forbid it again. maybe in the future our spectators (both men and women) become mature enough but certainly today is not that day.
I wonder if you have ever watched the live foreign volleyball games in our TV?! headache is the only way I can describe them.
