Here, let me finish that comment for you: "Gotcha! You don't read this one specific (if very prestigious) journal I can name and aren't familiar with its particular foibles, so you must not be able to provide any evidence for your claim!"

Actually, there's really only one big politicized issue in the natural sciences, not counting ethical concerns in biology (I'll let you figure out what it is on your own). This is unsurprising given that it's much harder to twist the facts to suit a narrative.

The social sciences, on the other hand, are full of politics. I don't have links handy, but X% of researchers in some social sciences openly admit to political discrimination in hiring decisions, for some large X.
