Ayn RandCollectivism requires self-sacrifice, the subordination of one's interests to those of others.
Ayn RandA man's sexual choice is the result and the sum of his fundamental convictions.... He will always be attracted to the woman who reflects his deepest vision of himself, the woman whose surrender permits him to experience a sense of self-esteem. The man who is proudly certain of his own value, will want the highest type of woman he can find, the woman he admires, the strongest, the hardest to conquer--because only the possession of a heroine will give him the sense of an achievement.
