Health, what you’re essentially claiming is that the APA forced through a policy that contradicted the available scientific data at the time, because of wanting to conform to societal pressure (or, to use your term, because they felt a need to be “politically correct”). And then, when NARTH presented them with scientific research that contradicted their position, they stifled it. Because, again, they wanted to be “politically correct”, so they abandoned all usual rules of governance, scientific methods, etc etc in service of this political correctness.
What on earth do you call that, if not a conspiracy?
