No disrespect taken. I'm really just trying to figure out how much thought you've given this subject. Weren't you the guy who had a whole thread on how any martial arts style will work if it's trained correctly? I think so, but may be mistaken. so, I'm just trying to figure out for myself whether you're just spitballing here, or if this is something that somehow relates to your definition of "martial art."o... k.
Taichi is ma as far as I know, Martial D thinks otherwise.
Then for iado down to catch wrestling I don't know enough about them.
For example I know Kendo was constructed as a sport but having never trained it I don't know if the jitsu elements are taught or not.
Sambo and catch wrestling I know nothing about.
Then from ninjutsu to Kali are martial arts except for fencing which is a sport based on martial art.
Again, no disrespect to sports just different things.
And it sounds like you just may not be familiar enough with the diversity of styles that exist, and so it's a little easier to take a binary stance. My opinion is that it's very mushy, where you have sports that evolve into martial arts and martial arts that evolve into sports, and every possible permutation in between.
