I find it hard to imagine how it would be to not have any memories or not to know simple things like colours or the feeling of sunshine/snow on your skin. In chapter 13 Jonas and the Giver talk about making choices, and the Giver justifies the fact that the people in the community aren't given the power to make a decision with the possibility that they might make the wrong choice. I think that isn't a very persuasive reason, because in my opinion people need to make mistakes in order to learn for their future and to grow from them.
The concept of sameness doesn't appeal to me, I mean it's true that the bad things, like war, are disposed of, but what would life be without the beautiful things like butterflies, rainbows, sunsets and the feeling of warm sunrays on ones skin everyone should have a right to experience this comforting feeling.
I wouldn't trade the way things are now for that colourless and monotonous life in the community.cr: http://data.whicdn.com/images/7986588/tumblr_lhyl7oup9F1qdw3jto1_500_large.jpg?1300303422
