I have been following these people for quite sometime, so it really just clicked with me when Bari Weiss released the article in the NYT mentioning them as 'the Intellectual Dark Web'.
- Eric Weinstein
- Ayaan Hirsi Ali
- Sam Harris
- Claire Lehmann
- Douglas Murray
- Maajid Nawaz
- Jordan Peterson
- Steven Pinker
- Joe Rogan
- Dave Rubin
- Ben Shapiro
- Lindsay Shepherd
- Michael Shermer
- Brett Weinstein
They are mostly a collection of disillusioned liberals looking for a place to have honest conversation about things that others aren't willing to have. They do not form alliances based on their identities or tribal affiliation.
As soon as the Intellectual Dark Web (IDW) appeared (Bari Weiss NYT), so did accusations that its members are all closed-minded and politically partisan.

What do liberals have against this eclectic bunch of individuals?

They are not getting any hate from the right.
In particular Dave Rubin a fully fledged gay leftie, bordering on socialist, nicest guy in the world, willing to have a conversation with anybody, yet the vitriol he receives(from the left) is quite disgusting.
