I sympathize with the overall thrust of this comment, that we should be skeptical of LW methods and results. I see lots of specific problems with the comment itself, but I'm not sure if it's worth pointing them out. Do the upvoters also see these problems, but just think that the overall point should be made?

To give a couple of examples, take the first and last sentences:

I think the recent surge in meetups shows that people are mainly interested to group with other people who think like them rather than rationality in and of itself.

I don't see how this follows. If people were interested in rationality itself, would they be less likely to organize or attend meetups? Why?

Which wouldn't even be necessary if we were dealing with interested researchers rather than people who ask others to take their ideas seriously.

(I guess "interested" should be "disinterested" here.) Given that except for a few hobbyists (like myself), all researchers depend on others taking their ideas seriously for their continued livelihoods, how does this sentence make sense?
