The flagged comment is pretty inscrutable but I think I can explain the overall sentiment a bit better: half the country is under the impression that much of the science spending in this country is wasteful or even pernicious. They hear stories about studies of "racist highways" and "periods in transgender men," or the CDC claiming racism and gun control are diseases it should control, and think "why am I paying for this?". Combine this with the perception that the science establishment really shat the bed in their response to covid--lying about its origins, lying about the efficacy of masks, lying about the efficacy of the vaccine, lying about two more weeks, pushing ineffective and harmful lockdowns, etc--and half the country is ready to burn the whole thing down.
I, personally, know that science in general is a great good and should be funded. But the craziness, corruption, and dishonesty have to be excised or people are not going to support it.
To your comment in particular, the people supportive of these cuts don't think they're dragging us back to the dark ages. They think they're excising a tumor.
