You can say it to them, I'm just saying I don't think it'll be effective in getting him out of his "delusions". Some of the more fundie, baptists and evangelicals are tought to key in on theese hard lines and it will encourage them to proselytize. I would just word it a little different like from :"You nor anyone else will change that" to: "You're not to convince me with that bullhorn you call a mouth" .. or something like that.
