You hit the nail on the head. I don't know and have no idea at this point. That's why this forum caught my attention and led me to ask the question. And made my humble suggestion, having worked on some forums I can see where some just need to be re-thought or re-arranged, that's all.
I do consider BJJ western as it's from the 'Western Hemisphere', others may not since it's 'South American. It is judo which is Asian, but like you said, heavily modified. But it's influenced by the Brazilian culture and needs, so it's western. Or isn't it because most of us know "western" as the US, Canada and Western Europe.
I've also only though of Martial Arts as KArate, etc. based - from China. Fighting techniques from Europe could be considered but that's above my head.
So you can see where definition is important and where I am confused.
You make good points about what to consider, maybe the moderators can help out.
The actual content of the forum versus the description seem to be at odds. See multiple posts on Iraq, ammo, air warfare, politics, WMD, etc. Throw in confusion about Western Martial Arts and there are the making of a nice long thread.
I've obviously spent more time on this than my boss would like so I'll check in later. Thanks.
