Visit http://english.thekotel.org/. Note the section header “Bar/Bat Mitzva”. Click on it. Search the entire section for any mention of celebration of a Bat Mitzva ceremony at the Kotel. If you find one, let me know, because I sure couldn’t. I’ve therefore just sent the Western Wall Heritage Foundation, the owners of the site, a message indicating that although my family has supported them in the past, we will refrain from doing so in the future.
