Like this is because of discrimination?
Let me try an exercise in progressive/LGBTQ logic.
Yes, it is because of discrimination. Clearly there is a disparate outcome in the frequency of HIV/AIDS in the pervert and intravenous drug users' communities. Disparate outcomes (a term of the art for liberal lawsuits against the normal--e.g., school discipline, or mortgage lending) are... BAD.
Now, if the above mentioned communities were free to donate blood, many more people would be infected, and the disparate outcomes would be diminished. That would be GOOD.
See how prejudice keeps LGBTQ and intraveneous drug users from contributing to their communities via blood donations, and also "causes" their disease rates to stay higher than those of other groups? Do I need a /S?
Well if "the law of gravity is racist" then virus's certainly are. Light from the sun is probably also racist.
