Utopian or unconstitutional?

There are so many technological advancements in the entire Divergent series. However, i'm not entirely sure that I would ever want these particular advancements to happen. They can erase your memory, change your genes, give you serum so you can tell only the truth. They call this a utopian society, but I call it unconstitutional. They take away everything you have ever known. They force you to tell the truth about everything. You are supposed to have a freedom of speech so that you can voice your opinion and talk about what you want to talk about. You should never be forced to forget your childhood or tell your deep dark secrets to the entire society. Why would anyone call that utopian?
