I agree that it is time to repeal outdated laws that make it a crime for a person infected with HIV to spit at, bite or throw his or her blood on others. However, your editorial wrongly excuses those who enacted those laws.
You reported that such laws "might have seemed reasonable at the height of the AIDS panic." They did not. They contributed to that panic. I should know, for I was already enforcing Los Angeles' landmark AIDS anti-discrimination law, which combated such fear and misinformation.
When those laws were enacted, the U.S. Centers for Disease Control had already concluded that "AIDS is a blood-borne, sexually transmitted disease that is not spread by casual contact."
