[0]: see My Immortal if you want to witness Harry Potter and Twilight get butchered at the same time.
Before reacting to what might seem like flame bait, I tried to stay in style to the article and would like to point out that the ‘gag worthiness’ is intended and part of the joke.
Perhaps a subset of HN is just excited to take the "rationalist" movement down a peg, which I suppose is a positive development.
But it's a lot like the vitriol I see towards effective altruism. There's a good idea there (i.e. wanting to train oneself to think rationally, or wanting to do charity in a way that achieves the most good for the amount of money given). It's a bit sad to me that because the representatives of these ideas are flawed (rationality, LessWrong, Eliezer), or because they've been used as cover for shitty behavior (effective altruism, Sam Bankman-Fried) that the consensus becomes "there's nothing good here and it's all bullshit".
This pattern of throwing out the baby with the bathwater seems absolutely pervasive in modern discourse, you can see variations of it in people's thinking on vaccines, racism, democracy, journalism, freedom of speech, and global warming, to think of just a few examples.
Sorry, this became kind of a rant, but I really wish our internet discourse could do a better job of filtering babies from bathwater than it currently does.
