I was a kid in the 80s living provincially at the arse end of the planet - far away from any excitement, or really any sort of socially progressive views.
A young girl and her family moved to our area in the mid-80s. She’d been born prematurely and given blood transfusions. She contracted AIDS as a baby, and was so ostracised from her community in Australia, she and her family left the country and moved overseas when she was four. That’s how bad things were back then. Even small children were shunned.
Luckily she was welcomed with open arms into the new community, and lived a relatively normal life until she died aged 11. I remember genuinely thinking she was going to be OK and love a more so life. But of course that was impossible then.
In a way, I don’t blame people for panicking when a new deadly disease emerges. It is human nature. It’s scary. I think it’s easy to look back with hindsight and say we’d never behave like that. Maybe we wouldn’t - but plenty of people would. COVID (pre-vaccine) was bad enough, as it is very contagious. But it’s not all that deadly (albeit plenty of people did die in the early days (and stop do)). But AIDS - while less contagious - was a literal death sentence. That’s terrifying.
As others upthread have said, what Diana did was genuinely monumental. It turned the tied. Recognition where it’s due - what she did was historical.
