It would not be the case with people that were alive and mature enough at the time to be cognizant of the situation. I think the OP is referring to people who were not around at the time...
Not to mention that HIV/AIDs is no longer the death sentence that it used to be. So even among those who are cognizant of what it was like in the 80s, they also know that it isn't like that anymore.
It's still crazy to expose yourself to the virus. The antivirals you get for HIV infection have lots of nasty side effects, and even with treatment you're still likely to die well before your uninfected peers.
