Who cares what other people think of Aikido?
Why would you even be concerned?
Amen. You know what you want to do and what you think. Some will agree and some won't. Don't let online discussions bother you too much. People will vote with their feet; those who don't want to train in Aikido won't go there. It's telling that I have never had such debates in the real world.
As long as you enjoy it and think you're getting something out of it, that's all that really matters.
Now, all I have to do is follow my own advice!
