I was trying to report on the opinion here in the UK - not only of Obama continuing to talk during the anthem, but his behavior in failing to actually toast the Queen, which is totally unacceptable. A simply sign of respect for your host, totally ignored.
If my word choice offended, I apologise, but it was honestly the only word for his behaviour that sprang to mind, having been bandied about quite openly on the various political boards here.
Don’t take Obama’s behavior personally. He disrepects our own anthem, as well.
