Lousy title, I apologize, but sometimes it is hard to fit an idea into a title. The question really is, how important is full contact training for preparing oneself for self defense? There is a school of thought that I think quite logically states that you need full contact so you get used to taking blows should a self defense emergency arise. There seems to be a concensus that normally when you are attacked you will get hit, hence if you arn't used to taking blows you won't be hardened or tough or prepared enough to take a blow should you be hit when somebody attacks.
Than there is a school of thought that states that what really works in a self defense emergency is too dangerous for full contact. That to train or spar full contact using techniques that "really work" would result in the practitioners being maimed or killed every class. That would of course be completely unacceptable.
What do I think? Well, I'm kind of confused to be honest. I think there are merits in both arguements. So I ask those who know more, what do you think?
I think it would come down to how you want to train and what you want out of your training. If you're in it for the purpose of meeting new people or something to do after work, and nothing more, then contact really isn't an issue.
If you're in it to learn to defend yourself, then yes, contact needs to be a part of that training. Better to get used to it in the dojo, than find out when your life is on the line. Sijo Emperado (Kajukenbo) had a saying, something along the lines of..."Make pain your friend, so when it comes to visit, it won't be a stranger."
Now, I believe that when you're new, the contact should gradually be introduced. In other words, if you're a white belt, there should be either no contact, or very light. The arts are a contact activity, so IMHO, if someone can't deal with it, then perhaps they should find a new activity.
I'm not saying that half the class needs to leave on a stretcher or head to the ER afterwards, but my God, once you reach the upper levels, hell yeah, there better be some contact!
As far as the too dangerous thing goes....lots of things are dangerous. We dont choke out or break limbs during grappling, every session, but you still train those things. Pad up and fight or run thru your techs.
