Why is a culture that mistreats Women so, allowed the largest Immigration numbers in the USA? - country with the largest women

Apparently after the San Francisco Chronicle. World section yesterday, the Mexican women who are of Mexican men harass so bad in public buses and trains that carry only women in the car.
Only women can travel in these cars to prevent abuse by people.
This also applies to Brazil, Ven. and Japan and some other low-income and South America.
WHY can not exceed 50% said the legal immigrants from Mexico and that have additional Central and South America, seems to have little respect and concern for the rights of women, including her own?
How can it benefit our country? What can we expect, but more crime and abuse at the hands of people like these new recruits. Moreover, the illegal crowd, knowing that come here illegally. Whimagine that our future is with the people and our people back into the numbers?
