They don't deserve a single iota of respect, are a total joke & nightmare for the world, feeding lies and disinformation to the world. Would be plutocrats Koch Brothers, Harlan Crow, Leonard Leo of the Federalist Society, Chris twitter-poster-shit-show-freaking Rufo?! A whose who of extreme conservatives eager to get us back to the 1850's. Here's some sites from about covering them, in gentle neutral terms, but Manhanttan Institute absolutely deserve more serious lambasting & being laughed out of any polite company. Ad hominem maybe, but absolutely people working in opposition to a better world, trying to drag us into a corporate controlled hell world, and deserving of no regards.
