I can't see how it's any business of non-Egyptians to line up on either side in this situation, or speculate which side we'd be on if we were Egyptians.

If we were in a situation where there was an orchestrated attempt to get public opinion on the site of the (post-coup) opposition, with a view to helping them achieve power, as has been happening in the case of Syria, then it might indeed be relevant to draw people's attention to some of its more unpleasant aspects, such as attitudes towards FGM. But at this point that isn't happening.
