I was just wondering, that it seems Islam provides too little by way of cultural stuff that other people accept by free choice, rather than coercion.
I mean, so many non Western women(& it seems a majority of men), all over Japan, China, much of Africa & India, even Islamic nations like Turkey, Tunisia, streets of Dhaka wear western clothes, extremely few, if any have adopted Islamic hijab & niqab. Christian weddings are popular amongst all Japanese, although the overwhelming majority of Japanese are Shinto-Buddhists. Japanese Anime & manga comics, are popular amongst many people globally, & the Korean cultural wave found many takers globally, including in Iran. Indian movies and soaps are very popular in Pakistan & Bangladesh, & the Afghan Government had to ban Indian soaps on the charge that it was an insidious attempt to "spread Hinduism."

Yoga finds many takers globally.
African American music like jazz finds global takers, Latin American dances like salsa & hip hop do too, Morocco held protests about Latin American dances.
Christian festivals like Christmas are celebrated by plenty of non Christians, I've seen grand celebrations in India, Singapore etc, few non Muslims celebrate Eid.
Islam, compared to its population size, has few exportable cultural stuff, & I don't see many things catching on, I mean, I don't think that the world is going to take to hijab en masse, & exportable stuff like belly dancing is branded haram by Sheikhs.
This is imo, one reason for Islamic insecurity, that the culture(and Islamic culture is a huge part of the religion) they aspired to make global is finding so few takers, & so many rejectionists!

So we have all these foolish fatwas against Picachu, against yoga etc, in a desperate attempt to stop Muslims themselves ditching Islamic culture.
