I suppose I study mainland-style karate; there are a couple portraits of Funakoshi-Sensei in my dojo. I don't think it's too watered down (my Sensei puts an emphasis on self-defense in training). If I want to train harder, I can. Those who do not tend to suffer in the long run. That's just the way it is at my dojo. There are white belts I have a tough time with and blue belts I can pound to a pulp in sparring. Thankfully, my Sensei evens it out with thinly veiled threats of demotion for some and encouragement for others.
I regret that I have not been able to attend the dojo in the past few weeks; my parents will not allow me to attend class until we can afford payment. It isn't much, and my Sensei doesn't mind, but....>.< Thankfully, I still have enough sense to train at home.
