It is completely inexcusable that people in STEM fields are so reactionary, considering how capitalism utterly destroys science.
If universities were actually "left wing indoctrination factories" like the right thinks they are, every STEM grad would be taught, for example, what Kropotkin had to say about innovation.
There is no such failure. Nuclear fission has caused the least death and disease of any kind of energy, per Wh produced. You still haven't said what exactly you'd pick, so that we can compare.
About 4 vaccinations per million end in death. This means that 1000-5000 people die of vaccination every year and 10-100× more (depending on the vaccine) have non-deadly complications. And still vaccinations are good, because the alternative is worse.
Compare this number to the amount of people getting power from your local fission power plant, and the amount of people who died because of it.
