Anything can be labeled a symbol of hate. Obviously the Confederate battle flag will be so classified, but the US flag could soon follow. Muslims may say that a cross is a symbol that must be banned...but the ACLU may have gotten rid of all of them before they have time to complain.
I am thinking that anything that bears the name of Thomas Jefferson and George Washington will soon be removed because they committed the greatest sin known to man...to own slaves, voluntary or non-voluntary...
