There is a genetic condition where cilantro tastes like soap to about a quarter of the population. Washing kids mouths with soap is/was a common punishment for saying dirty words. Collective punishment is a war crime according to the Geneva convention.
Is putting cilantro in a communal dish that will force people to essentially be punished by having soap in their mouth technically a war crime?
I flat out love cilantro. I think the courteous thing to do would be bring a small bowl of it and place it next to your potluck dish so people can put however much they want on it. The correct amount is a lot.
You can have all the detergent flavored parsley
