Re: "Aikido is BS"
The longer I train, the less interested I am in this kind of question.
If you're going to really, seriously attack me, then you're not a friend and so I don't much care what your opinion of aikido is. I'm going to handle the situation to the best of my ability and let the chips fall where they may.
If you're a friend, or someone else who is politely curious, I'll invite you to the dojo and let you draw your own conclusions.
If you're a student in my class, I might demonstrate some of the less polite variations that lie inside the basic techniques.
If you're a random person on the internet, I'll just yawn and go looking for more cat videos.
