"We are assured that Richard is not a "genteel" racist,"

No. he's definitely not a racist, genteel or otherwise.

He's critical of some of Obama's decisions not because he considers Obama to have reneged on some of his promises and thereby betrayed those who initially believed in him, but quite obviously because Richard is in fact a bearded misandrist.

In fact he's a misandrist lesbian polyandrist, which may also be clearly deduced from his political criticisms of your current married male monogamous president. All very shocking of course, but a racist he's not.
