The GayCityNews has information on how to register a comment on proposed regulations concerning the entry of people who are HIV-positive into the United States (comments close December 6):
Individuals who wish to protest the harsh new DHS regs on HIV-positive travel may submit comments online . . . — but to do so you must include the docket number of the proposed regs, USCBP-2007–0084.
Select the pull-down for Department of Homeland Security-All, and at the bottom, select Docket ID and paste in the number. You can read the proposed regulation as well as previous comments (which include such sentiments as “i oppose giving any visas for aliens with hiv. none should be given. the law as it stands keeping them out is a good, sound, healthful one. there is no reason to change it.” and “I OPPOSE ANY CONSIDERATION OF CASE BY CASE BASIS. KEEP ALL WITH HIV OUT OF THIS COUNTRY.” Such are our fellow citizens.)
(Hat tip to Andrew Sullivan for keeping this before us.)
