I would posit that the main problem with the WOW movement is that it is being done for two reasons:
1. To establish that women are as capable of men.
The entire basis of this argument is flawed. They are bringing feminist agenda into a place of non-issue. Judaism doesn’t say that women are less worthy — if anything, women are held up as the highest standard of spirituality. Women are innately spiritual, therefore, they don’t need the time-bound mitzvos as much as men to keep them focused on Hashem.
The problem is they are making an issue where there is none. They are bringing in non-Jewish ideas and applying them to Judaism. They are fighting against Hashem, with them making the war — not Him.
2. They are going contrary to tznuis, drawing tremendous attention to themselves.
Whether or not they are breaking any specific halachos, they are going against the very essence of Judaism. And all because they’ve absorbed the goyishe concepts that posit that women are less-than men.
