I really don't care to discuss the political views of someone who donated to the institution, if we did that with everything we'd never be able to have a discussion about anything again. Attacking someone who had almost nothing to do with the video's production is a ad hominem argument, and a bad one at that. This is a well researched video that goes through major trends in urban planning and what they think would work best to reduce the cost of housing and build better neighborhoods. I mean the basis of the video is talking about the genesis of Jane Jacobs and what she believes in, who is a major figure in urban planning and not some fringe player. If you have real criticisms of the video I'd have been interested in hearing them but if all you want to do is talk about Koch it seems like you might be more interested in a different thread
