1. Science has always been political, this isn't new. Some of the first major experiments were performed in Nazi camps. Cancer treatment began with torturing Black Americans. The entire idea of ethics is political in nature.
2. Science is still the search of truth. If it doesn't match your truth, then that doesn't mean the science is wrong.
3. Challenging scientific conclusions IS encouraged, but there is also a danger to it. Look at Covid. In the US alone, 500,000 Americans died from Covid. Challenging social distancing, masks, and vaccinations costs lives. I mean literally costs lives. The people challenging this were doing it for political purposes, i.e. most of them had absolutely no idea what the science said or how it might be wrong.
We have overpopulation anyway. And we don't have shortage of normies by any measure. In fact some social problems like monopolies are due to overabundance of normies.
