Is it possible that some are not as equipped as you are to discern the signal within the noise?
Is it possible you are incorrect about one or more of your heterodox opinions?
The type of sneering you're engaging in is unbelievably counterproductive. Uncivilized, even.
It's not just some innocent difficulty with finding the signal in the noise. It's sentimental, ideological delusion, and it's rotten to the core. And deep down, I believe many of them do know better, even if they stopped caring years ago.
I won't pointlessly anger them by saying so to their faces, but I also won't patronize them by pretending otherwise.
