This administration is both fundamentally anti-science and wants to enforce political control over all government institutions. Science was never a particularly stable work environment, but the sheer insanity you have now makes it a deeply unattractive place. You have no idea if your grant might be denied, or even canceled at any point later by some political commissar that doesn't understand science.
And it's not just particular topics they hate, they hate the entire system and institutions. And they try to either break them and force them to adopt their political views, or they attack their funding or use any other powers to dismantle them.
Science, or more specific to what we're talking about, public research which happens mostly in universities, has turned political long before this administration.
That's the simple reality. Administrations impose their politics, but also universities do the same, and they're not any more noble for doing so.
Research groups need to have more independence and that can only happens through a very meritocratic funding process, and also, at the risk of sounding like a STEM lord, by being very cynical and realizing that not all fields of research merit the same amount of funding. Countries like China have already realiezed this.
It is far worse than "this administration", the population in general are vastly undereducated, to the degree they do not even realize how serious this is.
There has been a massive, decades long educational failure in the United States, and probably the entire western hemisphere of culture: no where are people taught how to manage disagreement. due to that, we have this moronic destruction taking place where "idiots of authority" see no reason not to dismantle anything that irritates them, and nobody has the langage to explain nor the peer power to stop the desolation of our entire supporting infrastructure. All because idiots of power do not like being told and proved they are wrong. So, power removed the education that taught people how to debate without emotions, and here we are.
