All forms of racism, sexism and classism are wrong! Dividing peole into any class or group for the purposes of politics is wrong. It is a tactic advocated by Saul Alinksy (the original socialist community organizer) in his book Rules for Radicals (that Obama taught ACORN students from). All people are created equal in their rights and must be given equal opportunity to acheive and freedom to do so. People are not equal in their gifts, abilities, intelligence or drive. Individual differences must be respected and cherished. Its insane to try and make all individuals the same.
