Dear sir,
Thank you for expressing your opinion loudly out of your truck window. I apologize for the delay in responding—even though I was not the one being addressed—but your monologue has been turning over in my mind for several hours now.
So let me be perfectly clear: when the opinion you wish to express is "Buy American, you fucking Jap!", your opinion is not in fact welcome outside my house, nor indeed anywhere in my country. Your legal right to shout this does not in any way include a moral right to think it. Therefore, I'll thank you never to shout this in my earshot again, or anywhere else.
Yours etc.
