I agree that it was a rude, tasteless metaphor.
Alas, for rude, tasteless behavior, such as replacing your own authentic self-expression with the mellifluous spew of verbal diarrhea that bullshit machines slather across all surfaces they touch, rude, tasteless metaphors are the only fitting ones.
If only everyones authentic self-expression were so important to hear, to say nothing of unique and inciteful.
I'm not against authentic self-expression, but this is more about being wrapped up in ones own self-importance.
