your comment hardly addresses the writer's point that "NH-J can't stop being wrong about everything". Also note that "everything" is a very broad brush. It kind of covers....well everything. Then, to make such a claim, and not substantiate it (which is impossible by the very nature of the claim), well it reduces it to a platitude.
And to address your 'point', yes of course there are people fleeing Cuba in the hope to find a better life (everyone is aware of this... it's kind of ...a..platitude). And, again, I don't know what that has to do with NH-J not being able to stop herself from being wrong about everything. And I don't even know NH-J, AND I haven't learned anything about NH-J. Not from the writer, nor from your comment.
