Absurd.

Keith decides that it would be helpful to offer an explanation.

He provides ONE possible explanation.

(a racist one)

He makes no attempt to draw our attention to any other explanations.

He just stands up for the racist explanation he has provided, whilst simultaneously claiming indemnity on the ground that it wasn't him who thunk it up.

All Keith ever did was fight to the bitter end to defend it on a public forum.

Spineless and dishonest ... you should become a politician.
