Some gay men just don't get it.
They go around boasting of their "disease-free" status like it's a badge of honor, a degree they earned, or an award that makes them a better person.
In reality, a gay man using terms like "disease-free" and "clean" is an ignorant and insensitive man.
If I could tell him anything, I'd tell him Why the Term “Disease-Free” Hurts My Feelings.
