Is there a regulation/message regarding the so called inspirational/uplifting quotes people attach to the bottom of their official emails?

i like em. but i can probably guess that you encountered one that could be construed as offensive. i have too chief. i tried to stop looking at them as if the person were saying them to me. but it really didnt do much. the regulatory guidance is vague. there was a male that had a quote that could be offensive to females. and one did in fact get offended. the IG/EO office came down to give us a little spew on these added quotes. i dont remember what policy he was using, but there are limitations as to what you can put. offensive in nature, curse words, degrading to race, religion, gender, sex orientation, etc. this was at fort bragg. maybe contacting their EO office would help you find what you need to find.

after years of going against the grain, i finally joined the march and have a quote too. lol. dont judge me. however, let me know if this is offensive to anyone so i can adjust.
"Be without fear in the face of your enemies, Be upright, that God may love thee, Speak truth, even if it leads to your death, protect the innocent and do no wrong. that is your oath"
