Have you read works by major American Conservative authors like John Adams, John Randolph of Roanoke, Russell Kirk, Robert Nisbet etc?
Exactly what neoconservatism and Marxism have to do with this I don't know. I think you are confusing anything that is not individualist in the classical liberal sense with Marxist style Collectivism. That is nonsense and makrs you out as being what Americans call libertarian rather than Conservative. No Conservative is an individualist in the way you use the term.
