Weaponizing "Open-minded"

I realize I'm participating in an occasionally problematic trend when I say that something has been weaponized. These days, more and more things are said to have been weaponized:

But one term that I really do think has been weaponized as never before is the term "open-minded." For proponents of pseudoscientific practices (like, say, Facilitated Communication, Rapid Prompting Method, and Spelling to Communicate), open-minded seems to mean, specifically, open to pseudoscience.

That is, if you insist on scientific evidence and rigorous, controlled testing, you have failed to be open-minded.
