I imagine many of us are aware that it's military protocol to address men as "Sir" and women as "ma'am". Even if we weren't aware of such conventions, we still would never consider taking offense of the use of such a formal and respectful manner of address. Not so for Barbara Boxer, Democratic senator for California.
Bear in mind that Ms. Boxer has been cited as being "perhaps the personification of the feminist left" by the Almanac of American Politics.
All I have to say concerning Ms. Boxer's rudeness toward the Brigadier General she was questioning is, "Learn some respect, MA'AM".
