The one thing they won't do, criticize their own beliefs.
And why hate? This idea leads us to a utopian ideology that is not achievable. I am having a mental picture from the 'The Giver' of them getting their injections.
The people of Jonas's community don't understand genuine emotion or pain, because their lifestyles allow no opportunity to experience it. Birthmothers are not allowed to raise their own children. Sex is forbidden and sexual urges medicated away. Adults are not allowed to choose their own spouses. Identical twins are not both allowed to survive because they would be too close emotionally. Every decision made in the community serves a purely practical purpose and is based on the rules set down at the time of the community's establishment, promoting Sameness and leaving no room for sentimentality.
