yeah you got me on one of those. The lower case 'l' is intentioal disrespect for a demi-god of the political correct of both right and left. The simple fact is the man was just in no manner shape or form what he is held up to be.
The lower case 'n' though means no disrespect and is correct. north and south (lower case) are directions but the SOUTH is a place with certain cultural, demographic and political aspects in common. A northerner lives in the north, a southerner lives in the south. But a Southerner lives in Dixie and pocesses certain cultural characteristics and familial ties. You can speak of a New England-er a New Yorker or even a Mid-Westerner but a Northerner? Sorry, but there ain't no such animal. Unless maybe you are talking about "Nanook of the North".
Holy ****........
