It is a shame then, maybe it is my belief that words are tools that has me concerned that terms and history of the life has gone so loosy goosy.
There was a group in Colorado that was teaching their newbees that BDSM started after WW2 by black gay men. That is what frightens me, if we don't know more about what we do and who we are how will anyone ever understand how dangerous our form of play can be.
