It appears that the author of the letter was trying his hand at satire. I guess he was trying to show that the Second Amendment is outdated, just as he's suggesting that the Third Amendment is outdated.
In any case, he's no Jonathan Swift and should probably at least give up satire for Lent, if not permanently.
He's also wrong about the Second Amendment, but we already know that.
Nothing here worth talking about.
