Abstract
Since the end of the 19th century, three combat sports – Boxing, Muay Thai, and
Mixed Martial Arts (MMA) – while different from the point of view of their respective regulatory
frameworks and of their technical specificities, have alternately become the target of analogous waves
of criticisms, even of “moral crusades.” These are a product of converging discourses of
stigmatization coming from policy-makers, from sport managers, as well as from journalists. In a
recurrent way, these activities have been accused of being extremely brutal and contrary to the values
of sport, and, more so, of degrading human dignity. Formerly deemed to be illegitimate and
immoral, Boxing and Thai boxing have been, however, each in its turn, progressively accepted in
society, recognized as sports disciplines, and considered as having educational potential. Nowadays,
the diatribes mainly focus on MMA. The objectives of this contribution consisted of specifying the
socio-historical circumstances of these denigration campaigns against combat sports, between
permanence of criticism and periodic reconfigurations of the targets, as well as understanding the
social factors underpinning this. In this respect, we formulated the hypothesis that the successive
focus of condemnations on these three disciplines could be understood at the interface of an effect of
social stigmatization of their participants coming from the most marginalized social backgrounds
and of the necessity to define, in a context of axiological crisis, a consensual standard of moral
monstrosity.
