I have absolutely no issue with Obama, Bush or anyone else "bowing" to British, Saudi, Japanese or any other royalty. Diplomatically, it's simply a sign of respect for the cultural traditions of another country. I do draw the line with puking on them, however.
Regarding the Salon source, I'm actually not a reader of their mag, but have read and heard this identical scenario with regard to the genesis of the mosque kerfuffle. This link just happened to paint a pretty clear picture. Are you disputing it factually, and if so, please link to your source.
Actually, I have not once attributed blame to Dubya on this thread, nor do I think anyone else has. If there is anything whatsoever to say critical about Dubya with respect to this mosque (and there probably isn't), he should speak out against the xenophobic BS that underlies this contrived controversy. His State Department deployed this Imam to the Middle East because he was supportive of the fellow's moderate views. Now he is sitting quietly while the right wing xenophobes of his party are throwing his erstwhile emissary under the bus.
