IMHO, it is hard to "show" some one Aikido. It does look "fake" and "staged". It is in the experience of Aikido that one understands. When I have applied a gently Kote-gaeshi and people feel their spines move, or I gently apply Nikkyo and their knees buckle, they tend to appreciate it more.
BTW, I have never used Aikido by itself in a real life situation. My fighting days were a long time ago and I was a lot dumber.
