Wanting the world to be a better place

Hello I am feeling so angry and upset about the way the world is and with people disagreeing with me on certain things like when I only say that I want the world to be a better place and saying things in which are not very helpful like when I say that no one should be forced to do something they do not really like or do not want to do as this is so wrong because we should all be allowed to make our own choices in our own lives. I just want to be able to do something to make this world a better place even though I am not expecting the world to be completely perfect or expecting people to be completely perfect either in which I understand that but I just want more positives and no more negatives like no more war, no more curfews, no more violence, no more bullying, no more disabilities, no more being told what to do as I am sick of it now and also no more people being so unpleasant or unkind to each other. I want to be able to write to the government about my concerns and be able to stand up more for myself and tell everyone how I feel. I really want more things to be done to make this world a better place and to prevent a lot of negative things like abuse and neglect and bullying. Also I want everyone to treat 18-25 year olds more as adults and for them to have more rights and freedom of other adults too.
