In 1988, at the height of the HIV/AIDS panic in the States, the GSS asked a bunch of questions about AIDS. At that time, 63.7 percent of respondents favoured a policy of “requir[ing] people with the AIDS virus to wear identification tags that look like those carried by people with allergies or diabetes.”
Any kind of requirement for unpopular groups to identify themselves publicly reminds me a bit too much of this:
Update: Even more disturbingly, most people who personally knew AIDS victims supported compulsory IDs. Here’s the breakdown (as an image, since I can’t work out how to do tables in wordpress; click for larger):
Disturbing. On the one hand, knowing someone with AIDS is likely to make the risk more salient. On the other, you’re supporting the branding of someone you know. The number of people surveyed with three or more acquaintances with AIDS is tiny, so it doesn’t tell us much; but I suspect knowing lots of people with AIDS is a good proxy for being well-integrated into the gay activist community, which should decrease support for tagging.
