Re: Why are you here on this forum?
I think the arguments that dominate the forums are generally between the two extremes that either argue that Aikido is useless or that Aikido alone (that is trained in a mostly cooperative manner) is a deadly effective martial art. The former is certainly not true and the latter insults the intelligence of rational people with other training experience.
I personally view Aikido as advanced training most suitable for people who already have a solid base in another art, preferably one that involves some type of sparring. I do believe Aikido works, but most people's Aikido probably does not.
