Not too well versed on aikido but a buddy of mine after finding out I do bjj claimed that street wise bjj is a bad idea and suggested aikido instead. I don't necessarily disagree about bjj on the streets but it seemed that in his opinion, as a whole, it was a waste of time to train, but I'd much rather have some sort of ground fighting knowledge. Is it like judo with an emphasis on throws and some newaza? Not trying to incite a pissing contest, but could anyone with more experience defend or refute his point. From what I saw on YouTube (just technique demonstrations so it might not be the best point of judgement) it seemed that not a lot of resistance is being produced by the attackee.
