Hence what makes the views so irreconcilable. If words don't mean anything, nothing does. I can see the appeal of ruling out reality as irrelevant, but it's not consistent. My beef is with a common anti-belief, which is there is no truth, as it's the founding idea in a pernicious ideology that has produced this anti-conspiracy hysteria, which is the explicit effect of iterating affirmative conclusions from this negative premise.
The OP's entire problematization of conspiracy theories is insincere. Without a mutual understanding that originates from a belief in the possibility of both truth and meaning, we're just animals without humanity to one another. I acknowledge these distinctions because those stakes are too high to be so intellectually careless as to ignore them.
