Is this not exacty where all the discussions get fueled?
There is no agreement on the basic principles it seems. And there is little agreement on what exactly is martial effective. The latter is quite easy to answer: In Aikido there is always an escape, so it is not martially effective. Aikido was not intended to be. Aiki jujutsu is.
The basic principles for me are those that occur to some degree in every technique. (we emphasize shi sei, ma-ai and kino nagare).
But sure I agree with you there is often no need to distinguish between Aikido practise. One might argue that the only distinction would be Aikido and Tomiki Aikido because on the outset practise and intend is different.
Correct of course. Tomiki is where it seems that they strayed to much. The basic principles are to be centralised, extend ki, lead the opponent without using force and move using more than one orbits (not always though), principles that you can apply into non-resisting techniques. Putting aikido in competition is against both the spirit and the principles. If you watch how they do it, you'll know what i mean. I just see people resisting and grappling...And the goal and intend (as you also mentioned) of practicing changes also.
Aikido was meant to be martially effective and it is. In a real application you can immobilize, or project (through) the attacker according to the situation. You can also disarm him, technicaly is almost the same as daito-ryu.
