This type of subject would get a better reception over in Practical Tactical (that's one of the many sub-forums here at Bladeforums in case you didn't know).
Over in Practical Tactical you would find several mature and intelligent people who take the subject of self-defense seriously (I can't vouch for everyone over there, but there are several). In fact, and oddly enough, some of those very people have posted in this thread. But perhaps because your question was posted in the General Discussion sub-forum they chose not to take it seriously.
Sometimes self-defense related topics receive a certain level of scorn and ridicule here in the General forum. Of course, if you were to ask a question like "What's your favorite zombie killing knife?", such a question would be warmly and enthusiastically welcomed here in General and go on for days and ten pages or more. This is not an unheard of occurrence here in General Discussion.
