To be pedantic, and why not, it beats animosity ...
CFT,
The difference between the question and the answer only appears that way the animosity is a matter of opinion.
What a load of bull! I wouldn't touch HFY with a 10 foot pole!
KPM,
Anyone coming to that conclusion based upon conversations made on an internet forum is as irresponsible as they are narrow minded.

There is no need to speculate on answer to a question that is specific to a particular lineage that you can't verify the answer to without more awareness of the system itself. Since everyone here seems to have an opinion based on their own interpretation of the question and their understanding of "Gwai Ma" relative to their experience instead of dwelling on what you perceive as a negative add some positive feed back and answer what you believe "Gwai Ma" is and how it is used in the martial art you practice.
