Casey,
As the Dali Lama says, " Everybody has a right to be happy." He really does mean everybody, even the people he doesn't agree with. Common ground is found, and progress is made through dialog. A martial arts demonstration showing the power of chi doesn't necessarily mean someone is flexing their ego. Many years of hard work and focused study may be behind the skill demonstrated. Ego problems aren't limited to people involved in this activity. I think people that show interest in the concept of qigong, and are new to it, are open to learning more information about it. It is their free choice how to proceed. Knowledge helps people make wise choices.
