Reed came to mind immediately.
SUNY New Paltz might be an affordable choice (even good rates for OOS students)
And I’ll give you a strange idea that may or may not be worth considering…Fordham - Lincoln Center. You wouldn’t think of a Jesuit school as “hippie” but that campus does house the theater and dance programs so will have a good mix of liberal minded people. The school is strong in the liberal arts but it does have a large core curriculum that you may not like.
