I think that's something that needs to be proven. The grant process is far more complex than just "included a sentence", they're evaluated by experts too.
Meanwhile the solution is to ctrl-f for "things that might mean what I don't like". The solution is more arbitrary, unscientific, and "kneel to Zod" than even the described problem.
Also none of this accounts for the possibility that a study might include words like "minority" and actually be of value, but under this kind of ctrl-f style cuts ... it could never be studied. So what are we talking about?
Required words bad, banned words good?
