MSNBC's prime-time "town hall" on immigration reform yesterday exemplified one of the more unseemly elements of media bias: brazen political advocacy disguised as an "honest conversation."

Attempting to pass itself off as a forum for voices on all sides of the immigration issue to elevate the dialogue, "Beyond Borderlines" featured droves of liberal guests who dismissed, admonished, and overwhelmed only token conservative opposition.

From the outset of the program, conservative guests were disadvantaged and drowned out. The "conversation," which touched on a wide-range of issues related to immigration reform, was steered by hosts Lawrence O'Donnell, who is a self-described socialist, and Maria Teresa Kumar, who is executive director of Voto Latino, a liberal immigration reform group.

Mike Cutler, one of the few guests who offered a contrasting perspective on the issue, was repeatedly attacked by Kumar, who oscillated between the conflicting roles of questioner and answerer, and the other panelists.
