"Everyone will get the HIV regardless of how well an individual shelters."

This is factually incorrect. It is not unstoppable. There are functional procedures that have been shown to prevent infection, otherwise there wouldn't be a doctor or nurse left in the world that would treat victims.

Treat everyone and yourself as if they were infected, and undertake the necessary procedures to prevent spreading the infection. It's up to us - not our overlords - who survives the pandemic, and the totalitarian aftermath of the oppressive quarantines too.
