I think what's being argued here is the extent of the lean. What are the logical limits? Also, many of us are not interested in growing cookie-cutter trees which are the spitting image of someone else's trees. What draws Americans to the HOBBY is doing for one's self, one's own design, to the extent that we can express OUR will. This, verses listening to the teacher say, "You must do this, and never do that." If that kind of mindset doesn't drive westerners away from bonsai as a hobby, -just as young people in Japan are not taking up the art, I don't know what would. Ask yourself what kinds of people would be drawn to bonsai: people who want to be told what to do? I don't think so.For the life of me I can't understand the virulent resistance to the obvious with this. Forward lean in a trees adds perspective, subtle, yeah, but it's there. Simple artistic technique used for literally hundreds of years in Western and Eastern art.
I like "pretty" trees, feminine I suppose, and deciduous. I can easily respect others that like rugged trees like JBP that emphasize age. You can characterize it anyway that suits yourself, but we want what we want, even if it's a little cockeyed according to other's taste. Hard and fast rules will drive away exactly the kinds of creative, free-spirits that should be attracted to bonsai. Even if @rockm wasn't wrong about perspective.
