Male oriented?

In martial arts, men usually have a distinct advantage.
Most systems were designed with the male physique in mind and often rely upon innate strength and aggression. 

Women may succeed with any martial art, but why train an art that doesn't favour the female body? 
Why not train an art that prioritises use of the legs, buttocks and torso?
Where composure is encouraged rather than machismo?

Betrayal

One theme that Master Waller has been talking about with female self defence students is the idea of being taught to 'betray ourselves'.

Consider school or work:

Our body says that it is uncomfortable. Our minds are bored.

Yet, we are told to remain motionless and endure.

We know we don't want to be there but we are are forced to remain.

Always at our own expense.

The damage to the body is small but incremental.

In many facets of life we are conditioned to suppress our genuine, natural, healthy responses in favour of somebody else's agenda.

This is one reason why the tai chi and self defence in our school puts such emphasis upon healthy, comfortable body use and easy, familiar-seeming martial arts responses rather than blocky, confrontational options.
