Gentleman
The True Gentleman is the man whose conduct proceeds from good will and an acute sense of propriety, and whose self-control is equal to all emergencies; who does not make the poor man conscious of his poverty, the obscure man of his obscurity, or any man of his inferiority or deformity; who is himself humbled if necessity compels him to humble another; who does not flatter wealth, cringe before power, or boast of his own possessions or achievements; who speaks with frankness but always with sincerity and sympathy; whose deed follows his word; who thinks of the rights and feelings of others, rather than his own; and who appears well in any company, a man with whom honor is sacred and virtue safe. - John Walter Wayland
Cad
A rogue, or bounder. A cad is a man who is aware of the codes of conduct which seperate a gentleman from a ruffian, but finds himself unable to quite live up to them. Cads are quite capable of disguising themselves as good chaps for some time, only revealing their true nature in circumstances of particular stress or temptation. Others embrace their caddishness whole-heartedly and delight in behaving in a manner which is, to be quite frank, not cricket. 

They are certainly intelligent, educated, often cultured and frequently very witty, but, alas, are simply unreliable.


Cesar Chavez - Gentleman

Eric Alterman is a cad.  He is arrogant, lies easily, ignores the tenets of the profession he practices. And he enjoys doing so. He gives every sign of delight with the power he has accumulated through a facile wit exercised to harm, never enlighten.  

Cesar Chavez was a gentleman, couragous, steadfast in his committments to doing right by others.
