Just last month, one of those Fools, TerryHogan, succinctly summed up the RXD bear case for our community:

First of all [UltraShorts] are just plain crap for long-term holdings. Second, I like health care in the U.S. I think Boomers, Obamacare, and [obesity] ... will be good for the health care industry in the states for the next 20-30 years.
