Our first idea on the rude Republican reaction to President Barack Obama's speech on Health Care Reform:
In the British Parliament, it is quite acceptable (and has been practically since Magna Carta) for the opposition to yell disrespectful things during a speech by the Prime Minister.
"Boo!" "No!" and "Fie for shame!" have been typical outburts since Dickens' time and, for all we know, Pitt the Elder.
History and literature do not recall anyone yelling "Your mother wears army boots!" but there's no reason to think it wouldn't be acceptable.
So if we Americans are opening up our Presidential speeches to insta-hissing, no doubt we will soon sink to the very depth and start maligning each other's parentage on the floor of the Senate. Which is something from which even Claude Rains desisted, in "Mr. Smith Goes to Washington".
