There was an article published that said 'Australian doctors' want martial arts/combat sports banned because they normalise violence.
Many viewers of the Kojutsukan blog will be martial artists and will immediately object to that assertion and may even be insulted by it, however, I counsel you to objectively assess all assertions. Something that is not generally encouraged in the martial arts.
Is there anything inherently wrong with normalising violence?
The general idea behind the Australian doctors argument is that by normalising violence you encourage violence from those that have been normalised.
Women's self-defence. Based on that argument, women who participate in WSD courses are normalised to violence and are therefore more likely to be violent.
Based on that argument our prisons should be filled with ADF personnel.
Never reject a proposition out of hand. Consider it objectively. It often helps to consider the proposition in another setting.
