While I agree with your sentiment a lot of men fought and died for and under those colors and I don't think I could bring myself to take a dump on them.
The coat of arms was used on the blue regimental flag of the 3rd New York Regiment in late 1777 or early 1778, even before it was legally adopted by the legislature. It was also presumably the principal feature of the regimental colors ordered by law to be provided to units of the state militia in 1786. The state militia regulations of 1858 provide for a white flag with the coat of arms, 10 x 12 feet, as the state flag and a blue flag with the coat of arms and unit designation as the regimental color of infantry and the standard of cavalry regiments. During the Civil War period, the New York coat of arms was impaled with the U.S. coat of arms on unit colors as well as on uniform buttons and other accoutrements of New York troops. The New York State Military Museum has an on-line exhibit of Civil War-era military flags at http://www.dmna.state.ny.us/historic/btlflags/electronindex.htm; that of the 14th Regiment, NY State Militia, has a particularly interesting rendition of the coat of arms.

the jerks who passed this law aren't fit to look upon much less fly a flag with such noble history and so much blood spilled for it.
