Because if the possibility turned out to be true, it would be extremely damaging at a social and political level. Not just on institutions, but on the psyche of people in general. I think everyone understands this at least on a subconscious level. There
must not be any truth to it, because if there was, it would do too much damage.
So why would I want people to discuss something that could potentially have that kind of impact? Because I want people to face all of the possible consequences for their choices, not just pick and choose which ones they will consider and acknowledge.
