“As I understand it, many newly infected people with hiv return a negative result. That’s quite a risk your advocating for.”

Since new HIV infections are also found in many people from groups currently “allowed” to donate blood (straight black women being the fastest growing group), if your understanding was the whole picture, blood transfusions would be extremely risky & dangerous. If we couldn’t test for new HIV infections in donated blood, then HIV infection from blood transfusions would be a lot higher than 1 in 2 million blood units.
The article you’re commenting on explains that “All donated blood is also subject to a rigorous RNA test which essentially detects HIV at the time of infection.” So it sounds like your reading on the subject may have been incomplete.
The author seems to be arguing merely that we be considered as individuals, with individual risk factors. For instance, I’m a cisgendered woman who’s exchanged sex for money & gifts, but my clients were also cis women, making my overall risk of having HIV relatively low, despite my automatic lifetime ban from donating blood.

You are advocating extending ‘Your’ rights no matter what the risk or cost to another :/
