I think nowadays a lot of people expect to get their own way. They may seek to have some form of validation for their course of action and when that conflicts with their own self importance they immediately baulk at the response. You only have to look at X-Factor/Pop Idol to see that many people are of the opinion they are important, they have a talent and deserve fame. They get up on stage and assorted 'experts' judge them and when it meets disapproval how many folks refuse to believe them? It's a wider situation than the kendo-world forum. Whatever happened to just wanting to be average? I am distinctly average [apart from the devastatingly good looks] and I get by in life just fine.
I like that view on the matter Kim. However i think ArcticBlizzard means the head-beating-to-the-wall type. I can understand they can be tiyring for some people especially when they spend time on a reaction and the asker just discards the answer. You could also just ignore the people that anoy you
I like to give beginners a sense of the reasoning behind why they should do something a certain way (e.g. why do you hold the shinai with the tsuru facing down when your holding it at your side). But there's a risk to talking to much. I prefer to spend the time having them do stuff rather than talk about stuff. Talking too much can sap the momentum out of practice. Sweeping over-generalization alert: The beginners who tend to ask too many questions don't seem to last very long. It's those ones who doggedly wash, rinse and repeat who tend to stick it out. Plenty of time for questions at second dojo.
