1) I can't help that your professor was an idiot.

2) OK, maybe you aren't actually an alt-right nutjob... But:

a) They're in the habit of spreading conspiracy theories about the CDC, and

b) They also often write "FED" like that.

You can blame your professor, not me, for making you look like one. (And yourself: How many years have you had to notice that his spelling is wrong?)

So there’s a few attestations for the all-caps FED listed here, including some from such sources as the IMF: https://en.m.wiktionary.org/wiki/FED

I guess you’re going to say the IMF are also idiots, and it’s the IMF’s fault that I “look like an alt-right nutjob”? In any case, it’s a hard question to research, especially since queries like “Fed capitalization” are ambiguous.

In any case, I’m not really inclined to take seriously the opinions of internet trolls whose only contribution is to call me an “alt-right nutjob” for criticizing the CDC and capitalizing FED. Your bizarre paranoia is not my responsibility and I’m frankly still not convinced that it’s actually wrong to capitalize FED. In my experience, people who issue bizarre and unsubstantiated insults to complete strangers over the internet are usually neither intelligent nor well-informed, and so you’ll understand if I don’t take your advice, or you, seriously.
