This isn't directed against a particular group or individual. It is to communicate about taking self-defense courses.
NEVER and I mean NEVER tell a Martial arts or Self Defense instructor about your history as a victim. Even a seemingly well intentioned instructor will put everything including sex under "self-defense training." The bad ones are like the ultimate predators. They will ruin you financially and otherwise so you have no recourse against them. And, they will use any law enforcement ties to protect themselves. There was one even one Dojo who used to rape women to initiate them into their next rank. One of the belted woman managed to sue the NY dojo for such discriminatory assault practices.
Additionally, if you are a woman of Asian descent, be even more careful because they will use your cultural background against you doubly. Because of some Asian gift-giving they will take everything from you even without your offering, your approval, or your consent. I have had this happen to me several times with an instructor. Everything from threats to "what's in the dojo stays in the dojo."
And then there is the perception that by paying your instructor the "fee" he asks will ease things.
Once you pay their fee they know they can get more out of you by hurting you extra in class if you don't comply with their outside wishes. Someone needs to define where the civilian instructor's position ends and his being a regular civilian begins legally. Remember, any men in the class are an extension of his ego as an instructor. He will rarely repromand the male students for any ill remarks or sexist behavior especially when trying to retain students in 'this economy."
Additional signs of being of women being abused by an instructor (I have seen over a 10 yr. period) include; women who actually commited suicide, women who turn into cutters (people who cut themselves to ease their pain) around the instructor, women who are frequently told to shut up when trying to voice a reasonable complaint or repromanded for "trying to cause drama".
Lets face it, many women go to safety courses to learn to defend themselves; not to walk into a roomful of ill mannered thugs.
