"If the Equal Rights Amendment were proposed today, would it go on to become a Constitutional Amendment?"

"The Equal Rights Amendment (ERA) was a proposed amendment to the United States Constitution designed to guarantee equal rights for women. The ERA was originally written by Alice Paul and, in 1923, it was introduced in the Congress for the first time. In 1972, it passed both houses of Congress and went to the state legislatures for ratification. The ERA failed to receive the requisite number of state ratifications (38) before the final deadline set by Congress of June 30, 1982, and so it was not adopted. Feminist organizations continue to work at the federal and state levels for the adoption of the ERA."

Think about it. 30 Years ago, did you ever imagine gays and lesbians being granted the right to legally marry? Compared to the ERA, gay marriage, must have seemed that much far afield, off the radar (to use a topical metaphor), a political impossibility.
I submit that the reason why the ERA didn't become the law of the land was because it's time had not come. Now that it's apparent time is here, why do you think it hasn't been picked up again?

"7 ridiculous restrictions on women’s rights around the world"

'"With Saudi Arabian women behind the wheel since Saturday to protest their country's refusal to grant driver's licenses to women, they’re challenging not only long-standing restriction, but also a the larger system of Saudi Arabian gender-based laws, some of the harshest in the world."

"According to one measurement, though, there are actually several countries that rank lower on women's rights than Saudi Arabia."

Here are other remarkable legal restrictions against women, from Asia to Latin America:

1. India (some parts): Road safety rules don’t apply to women.

2. Yemen: A woman is considered only half a witness.

3. Saudi Arabia and Vatican City: Women can’t vote... still.

4. Ecuador: Abortion is illegal, unless you’re an “idiot.” 

5. Saudi Arabia and Morocco: Rape victims can be charged with crimes. 

6. Yemen: Women can’t leave the house without their husbands’ permission.

7. Saudi Arabia: Women can't drive.
