@H2O MAN,
H2O man- you asked why they call names? The reason is obvious. They are unable to respond to facts and arguments. Joe from Chicago is a failed lawyer who hangs out at 26th and California trying to get sleazy dime bag dope addicts out of trouble. He doesn't have the smarts to debate.
And Setanta has been useless ever since his dog had a stroke and he volunteered to give the dog part of his brain. Since he was always a half-wit, he doesn't have much of a brain left.
If you pay attention, H2O man, you will note that whenever evidence and documentation are used to debate with Joe from Chicago( evidence of his incipient degeneration is clear when one thinks of the import of his avatar--a picture of the criminal Daley who urged police to shoot to kill--that is Joe from Chicago's hero) or to debate with Setanta, who, if truth be told is unable to discern the difference between Fascism and Communism, they both descend to the irrelevant.
