In orthodox Judaism women do not wear a tall it, teffilin or read from the Torah scrolls they are all reserved for men whilst there are other things that only women do. The Western Wall plaza area is run along the lines of orthodox Judaism but women are allowed to pray without interruption they are just not allowed to to put on things like tallit or teffilin or read from the scrolls. Another part of the wall known as Robinsons Arch has bee set aside for the reform ( everybody has something nobody has everything ). Women of the Wall is a feminist movement that wants to introduce secular feminist ideas into orthodox religion ( push their ways on others ) and these little stunts carried out by Anat Hoffman are designed to get her arrested and bring about publicity for her cause make it look like the whole country is behind her and the only people who don't want change are a handful of evil haredi which is not the truth. The majority of Israelis either don't mind the way the system works or they are dead set against change but because Hofman gets all the publicity and she is the one trying to fight to being about change not the one who has it their way already then hers is the only opinion that she comes out of it looking like the champion of the people which she is not. The supporters of orthodox Judaism are just as much entitled to have their place at the plaza as the reformers are entitled to have their place at Robinsons Arch.
