The HIV scenario is not equivalent. It was new, people were frightened and ignorant. There is no cure, no vaccination. Measles is a well understood disease that had been eradicated. Openly putting others at risk because of some nonsense belief should not be tolerated.
Are you good with a HIV+ person knowingly infecting others because it's their right to refuse antiviral medication? Measles and other highly contagious diseases can infect large populations without anyone knowing before it's too late.
I don't disagree with you and I trust you to make the distinction between the two things. However, I don't trust lawmakers/police/military to have the same sense of nuance.
