Cs, that version of what you said is better, but to secular people, “being of the same value”(which they are, Hashem loves women just as much as men) means equality in halacha and community. They consider it devaluing if they can’t lead prayers, wear tefilin, be rabbis, etc…
So what the Lubavitcher rebbe said did not address teaching the women the beauty of jewish femininity; the akeres habayis, the stronghold of emunah, the calm nurturing mother, the builder of klal yisroel, the daughter of Hashem – those are things beis yaakov teaches to inspire Jewish girls. And they don’t feel any less valuable because of it. Why couldn’t the Lubavitcher rebbe do the same?
