For opponents of JROTC, it's about ideology
Fine piece by Lauren Smiley on JROTC in the current SF Weekly, one of the rare occasions when it diverges politically from the competing weekly, the Politically Correct SF Bay Guardian, which of course supports the ban. The differences between the two weeklies are usually purely commercial.
The anti-JROTC website admits that the main motivation for opponents of the program is anti-Pentagon ideology: "The battle is far from over, and we are definitely giving the Pentagon a run for its money." Sure enough there are a number of fringe leftists listed as supporters of the JROTC ban on the site, including Cindy Sheehan, Medea Benjamin, and h. Brown. And, like a number of local "progressive" blogs, there are no names on the site to tell us who's putting it together. Local progs are often timid and like to run in packs.
