Israel is the homeland for ALL Jews, not just Orthodox Jews. Historically men and women both prayed at the wall and photographs show them praying in the same place. This was true until 1967 which is a very short time for "tradition". Now at all hours women are shunted into a small portion of the Kotel and if they want to pray with a Torah are shunted over to a side area away from the main prayer site in an archaeological site where worshipers must pay admission if they arrive after (:00 am. The 1948 Declaration on the Establishment of the State of Israel: “the state will uphold the full social and political equality of all its citizens, without distinction of race, creed or sex; will guarantee full freedom of religion, conscience, education and culture; will safeguard the sanctity and inviolability of the Holy Places of all religions”. Segregating women or the non-Orthodox to Robinson's Arch is a violation of that. There are enough hours in the day that non-Orthodox Jews can have time to pray close to the traditional site.
