A rambling, cursing tirade against a polite discussion of things that might be wrong with the group (or perceptions of the group) doesn't improve my perception of the group. I have to say, I have a significant negative impression from Grognor's response here. In addition to the tone of his response, a few things that added to this negative impression were:

"how painstakingly and meticulously Eliezer idiot-proofed the sequences, and it didn't work because people still manage to be idiots about it"

Again, the name dropping of Our Glorious Leader Eliezer, long may He reign. (I'm joking here for emphasis.)

"LW is a cult hur hur"

People might not be thinking completely rationally, but this kind of characterization of people who have negative opinions of the group doesn't win you any friends.

"since it's exactly what Eliezer was trying to combat by writing it."

There's Eliezer again, highlighting his importance as the group's primary thought leader. This may be true, and probably is, but highlighting it all the time can lead people to think this is cultish.
