Like any product or service there is good and bad Self-Protection So before you part ways with your time or any money, I would encourage you to do a bit of research before you start. Any credible form of Self-Protection should always emphasise the importance of prioritising your non-physical options including avoidance, awareness, conflict resolution and de-escalation prior to any physical applications. There should be teaching modules to include violence psychology, mindset, predatory behaviour, strategies and tactics and all should be presented with the correct context. What is taught should be based on research, evidence and statistics and when it comes to the physical components these should be gross motor, principle-based concepts and skill sets. You should feel free to ask questions, query things and disclose any prior trauma or apprehensions should you so wish without the risk of ridicule. All this should be the bare minimum you should expect from someone teaching Self-Protection, claiming their primary motivation is to help others over any potential financial gains.
