Aids was preventable with condoms or staying with people who didn't have aids, the effects of climate change can't be avoided (besides maybe being rich and moving).
Pretty much every bad thing you've mentioned is happening right now, but all at once. Abortion/ abortion drugs are banned in many states, Trump and ~70 million republicans made light of covid which caused far more deaths than aids and encouraged people to spread it, we have the most insane levels of corruption (j6ers got pardoned and paid 2b, Trump coin, literal insider trading by the president, supreme court saying something would be "inconvenient" in order to give unconstitutional readings). And the people supporting this are not some small whackjob minority, it's 70 million people seeing an American on the ground not moving getting shot by ICE and saying "he was asking for it."
