To follow more some of the essential idea proposed here, the study trades on the dichotomy or contradiction in that the spiritual emptiness and non-attachment of Buddhistic practice necessarily goes beyond identity (which is attachment), and therefore gender. The aim itself is toward genderlessness, while the social conventions which structure that practice are quite gendered and hierarchical. I would suggest that the very same thing exists in Thailand in terms of fighting. Thailand has a Fight Culture which celebrates fighting, or "chon" (clashing) in a pure sense. For this reason men fighting, children fighting, women fighting, chicken fighting, and even beetle fighting all participate in the same essential thing, the chon of spirit. You can check out Sylvie's articles on Bettle Fighting in the North to see aspects of this:
Muay Thai Clinch is Not Boring – Gwang Chon – Battle Beetles of Thailand - Part 1
Underground Gambling, Beetle Fights, Heart and the Clinch of Muay Thai - Part 2
These transcendent views are really part of the way in which Thailand can be very freeing for western female fighters. There is a real sense in which female fighters are just part of the chon of a universal spirit of battle, and that as long as the spirit is exhibited, it is celebrated.
A nexus point in a possible comparison between Thai Maechi and Thai Nakmuay Ying is the way in which there is an operative transcendent, gender-less apex of celebration, something which unites all participants, but also, a hierarchy of laddered social striation which can lead both also unreadable, or at least very hard to read.
