I figured out how to offend a manager at work: express concerns about Elon Musk. I was reprimanded for being "inconsiderate".
EDIT: No, I do not work somewhere that has Elon Musk in a direct or indirect supervisory position, including the board. The manager (whom I don't even report to in the chain) just didn't care for the lack of unconditional praise for Elon Musk in a slack thread.
I have the feeling "express concerns" here is a much softened description of what actually happened? Could it be that whatever you said would be inconsiderate regardless of the target?
What I said was actually just linking to his "pedophile diver" twitter comment, and a NPR article about his ongoing spat with the SEC. Definitely not the smoothest presentation, but I figured it'd be best to let more neutral sources speak than express an opinion in my own words.
And sure, if a person unconditionally worship someone, that person would probably consider anything that tarnishes the image of that someone as inconsiderate.
