No, there is not, because “exploration of identity or development” I take to be some kind of an expressive exception, but it's a very confusing term. I would suggest employing established terminology from other sections of the Criminal Code, such as the hate speech provision, which says that you can have conscientiously held opinions being expressed, and there's mention of religious texts and so on.
Just use the established language from other sections. Don't try to invent novel terminology, as the courts will have a hard time figuring out what that means.
