Re: techniquies in street fights
I tend to agree with the last couple of posts myself...you can fiddle with the terminology, but many styles of aikido definately include what might be termed as attacking/initiating movements. Budo does indeed list some great examples. Almost all the shomenuch ikkajo, nikkajo, sankajo, yonkajo techniques show omote as shite/nage attacking.
Even in styles where overt attacks might not be used, different phases of 'sen' are used in other ways. Not just go no sen, or reactive time/initiative.
