Islam and Christianity are two very different religions. Christianity is fairly equally split between Protestant and Catholic mostly, with many different sects intra-religiously that identify with both.
Islam, not so much. The vast majority are orthodox and support extremely conservative views she is in direct opposition to. Just in theory and principal, it's much easier branding her a hypocritical Muslim than it would ever be with Christianity, simply because there's a much more defined tradition for most Muslims.
Still, I haven't directly called her a hypocrite; only that she can be criticized. And this is what popular beauty contests are about now apparently, firing people up.
