There are a lot of people on this board who have a great deal of expertise on a remarkable range of subjects, including just about everything martial arts related and an incredible array of other topics. It can be a fantastic resource. Unfortunately, intellectual humility is in incredibly short supply and many members cannot bear to admit it when they are wrong, let alone to apologize. So, I, for one, appreciate your apology, though you never offended me.
Then again, I'm the kind of weakling who sometimes apologizes. You'll soon discover that this is the kind of site where members can take screening tests for narcissistic personality disorders, announce their almost-off-the-charts scores proudly, and then demand to know who these psychiatrists think they are to say that it is abnormal or bad in any way to have a healthy, positive self-image such as theirs without a twinge of irony, and they pretty much blend into the background.
There are a large number of cool, interesting, funny people to "talk" with here, but you may occasionally need some hip-boots to get through the machismo and self-adoration of a highly vocal and substantial minority.
