The Right Way to Hate

It amazes me how many ways the Right have found to hate people. Michelle Malkin today hosts rants about about "illegal" immigrants possibly collecting Social Security, "while ILLEGALLY using FRAUDULENT Social Security numbers STOLEN from actual, legal citizens of the United States of America," and giving "non-existent, unsustainable, budget-busting, generation-saddling benefits to millions of people who fraudulently entered the system by stealing the identities (and sometimes ruining the credit) of legal Americans?!?" She then links to a rant, "illegal aliens may soon be voting in North Carolina." Then she posts a quote of her own rant from January 7, 2004 which ends with this paragraph:
"The door is now open for all illegal aliens to collect retirement benefits using bogus Social Security cards. What's next: survivors' benefits for the families of the 19 Sept. 11 hijackers?"
Why feed hate to an already divided nation? What can this possibly accomplish? Why does the Right have such a high NEED for people to hate and fear?
