I think the absolute failure of the ERA has proven unequivocally that ratifying amendments to the Constitution are no longer possible in an age where mass media has broad and instant reach.
I don't see why not.
Older amendments have gone unratified before.
The longest spell between ratifications so far has been 61 years, and our last ratification was on 1992, so resuming now wouldn't break any records.
While ERA would have been a good one, we also have an older unratified amendment for regulating child labor.
The only reason ERA can't be ratified is that congress started setting ratification deadlines, but that's never been necessary, and older proposals that don't have them can still be ratified.
I think part of the reluctance is that people unaware that constitutional originalism is a fairly new legal theory (first proposed in the 1970s) don't regard the constitution as a living document when it has been for most of history.
They've come to see the US constitution as entirely up to the Supreme Court & forgotten that the ultimate control is the people & their power to amend it.
