::::: You're missing the point. Our definition accurately summarizes what those five sources describe. You seem to be implying that we must quote a source exactly. This is inherently ludicrous and has no bearing on any Wikipedia policy or guideline ever written. Could you specifically state what is in our definition that isn't in the sources? Pseudoscience is there - trying the change sexual orientation is there. What are we adding, exactly? Knowing what we're adding that the sources don't say could allow us to refine this definition.
