Aikido- good martial arts form if you want to know how to fight?

[snowbank]

I'm looking to learn martial arts. I spoke with someone in my area about Aikido, and what they said on the phone made it seem like it's what I wanted, but after checking on the internet it seems it's more of grapples and holds and things like that.

Is this a good form to take for example for a street fight or something like that?

I searched online for places in my town and the different forms are: Tae Kwon Do, Hapkido, and Kang Duk Won, along with Aikido. So I guess those are my options.

The person I talked with about Aikido stressed that many of the other schools mainly focused on belts and winning trophies, while his school taught to "kick someone's ass." Is this true? I could care less about having a belt, just interested in whichever form will allow me to "kick someone's ass" as he put it.
