Why is Barbara Fritchie not an American Feminist Icon?

After Confederate Troops marched into Frederick, Maryland (Yankee soil) and were given orders to shoot down all the American flags, a brave 94-year old woman stated (according to Whittier’s poem) “Shoot if you must, this old gray head…but spare this Country’s flag”. This was surely a bad-ass moment for women everywhere, but hold on! Barbara Fritchie is barely remembered today, is thought to have not actually done this deed, and (along with other female American would-be patriotic heroines) not recognized by modern feminists…why?
