benignuman: What you are saying is not entirely true. There was an article here on YWN just a few months ago about a Kol Isha problem that occurred.
Also, it may be true that only the strongest learners were the ones who learned in Europe. Your argument brings to mind those who argue that since there were so many women in Europe who didn’t cover their hair, woman today shouldn’t feel forced to either.
We are a nation that strives to perform the mitzvos. What one generation couldn’t do, is not a sentence for all later generations. 300 years ago it was uncommon for Jews to wear tzitzis all day. But today B”H hundreds of thousands of us are performing this mitzvah d’oraisa to the merit of us all.
