While I’m not sure what “neoreactionary” refers to specifically there are lots of reasons that certain types of liberals see LessWrong as reactionary:
A somewhat strong libertarian component
Belief in evolutionary psychology
Anti-religous (or generally the belief that beliefs can be right or wrong)
LessWrong’s more technical understanding of evidence is incompatible with standpoint theory and similar epistemic frameworks favored by some groups of liberals.
Those older discussions around PUA where it’s presented in a pretty positive light
