Even before 1948 there were no mechitzos.
You can talk agendas all you want, the fact is that they were doing this for 20+ years, in the women’s section.
There are far greater fish to fry and in the big game, this will just come back to bite the charedim, who are in the minority.
Whether the leader is reform or not, is irrelevant to WOW. Until they start protesting mechitzos, it’s a moot point.
In addition, protesting and making a scene at the Kotel kind of negates the point that the Kotel is not a place for protesting and making scenes.
Lastly, the Kotel never had a din of kedushas beis knesses so having a group of women davening, behind a mechitza, should not get people all worked up. Let them daven for the 20 minutes once a month.
