If you can't test something, how do you expect to convince somebody it's correct?. You believe ID for subjective reasons, as you have said. You don't think it needs to follow the accepted scientific methods of testing. So be it. You can believe what you wish. Don't pretend it is science though.
Some things are self-evident. Intelligent design happens to be one of them. Those who believe it do not need to be convinced they are right. If you can produce an example of unorganized matter that does not behave according to predictable laws, then you will be well on your way to establishing a reason to discard intelligent design as a self-evident, objective reality.
