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.

do you work at Tesla?

Nope. Just another average tech company.

Hmm... sounds like you got the short end of the stick. Off-topic conversations at work can be tricky, can't they.
