When academia has purged most Republicans, science can no longer be done. The point is to disprove hypotheses, nowadays academics ignore science and just twist data to show what they want.
Republicans scream at scientists and try to get them fired for doing climate science research, destroy funding bodies, pass legislation saying what professors can and cannot teach in class, and generally call the entire academic ecosystem a bunch of groomers. Fewer republicans choose to go to graduate school and become professors. This, somehow, means that research can never be done, justifying further destruction of academia.
I'm very sorry but I don't understand how not having a dozen race science people teaching about brain pans down the hall means my research is bunk.
