So you basically have no evidence to back up meaningless, unsubstantiated claims. You don't even support your statement: "affirmative action means women and minorities get preferential treatment during hiring." Guess the discussion is over since you refuse to provide any evidence to back up your ridiculous claims.
It's really easy to plug your ears and scream that an opponent's argument is "ridiculous" (what you are doing). It's more difficult to actually make a counterargument yourself (what you are not doing). Try harder, maybe.
