Islam, the Kaaba, the Black Stone, and Idolatry

http://www.answeringmuslims.com
Muslims often accuse other religions of idolatry. Yet Muslims bow down to a pagan temple (the Kaaba); they take a pilgrimage to this pagan temple (which is what the pagans of Arabia did before the rise of Islam); they walk circles around this pagan temple (which is what the pagans of Arabia did before the rise of Islam); and they kiss the black stone embedded in the corner of this pagan temple (which is what the pagans of Arabia did before the rise of Islam). Should our Muslim friends be accusing ANYONE of idolatry? Glass houses!
