Whoops, sorry, you didn't prove your point either. You just proposed it was not effective. You can't prove it either. Let's be clear. You asserted your position as fact. I asked for the proof and freely admitted I don't know the answer. I merely stated the case may not be as clearcut as you claimed.
You've since admitted that you have no data to back up your position. And hey, that's fine - neither do I. That's why I say up front I don't know. Until you do know, I suggest you do the same in order to avoid further confusion.
I guess I'm just a stickler for bringing data to support your assertions of fact.

Men that I don't trust are opposed.
I can't "know" everything but I can conclude enough to get to understand what is the best course.
