I have always been taught that Muslim worshipp cannot be considered idolatry itself, because they pray to Hashem, even if they call him Al-lah. But now I have found that a Gentile (Muslims are) is forbidden to point a stone or column as a centre of a meeting, even is it is done to worship Hashem. That is: Even a groups of Noahides who gather to praise G-d, in case they point a stone to mark the place of meeting, would render the prayer as idolatry.
Of course Jews cannot judge any Gentile idolator oitside EY. But it would mean that a Noahide is allowed to destroy Mecca. Since Noahides are thoretically allowed to use force, if neccessary, to prevent a another goy from commiting idolatry. What do you think?
If it is so, then any Gentile could bomb it.
