Keep in mind that amxf being more common than xmaf is not unique to indonesians and this was long before any asian media hype phenonmenon like the korean wave from the late two thousands decade. It's the same thing with other southeast asian ethnicities such as cambodians, viets, burmese, hmong, and laotians. For filipino dudes, it was specifically before the nineteen sixties, although they're recently catching up again like how they did during the first half of the last century and prior. Pinoys are returning with a vengeance. Regarding amxf overall outnumbering xmaf amongst indonesians, it's been that way for many generations, dating back when the dutch ruled over indonesia after two hundered years of colonizing the southeast asian nation and indonesia finally regained its independence in nineteen forty five, which continues nowadays.
