Re: Why are you here on this forum?
Not everything one reads is factual. Not everything one learns is useful. And not everything you see in a forum is relevant. That's life. Some folks enjoy being adversarial or confrontational online, especially if they desire impunity. You feed their need if you offer a reaction. Otherwise, they just leave.
I don't favor exclusion of non-aikidoka out-of-hand. Curiosity about the art helps to advance it, even if somewhat condescending. Outright disrespect does not work, but that is unfortunately not limited to the uninitiated. I try to take things with a grain of salt. I have seen other fora where people get banned whenever they say the first thing non-conformist. Personally, I like this way better.
Just one guy's not-particularly-important opinion...
