I don't believe that there is a cure for ms
Why do you think there is no cure for ms?
Because so many people have MS and don't seem to improve.
It is okay to disagree about some things but it is not okay to look down on others for believing something you don't. People will not want to spend time with you.
You should believe what I believe because I'm right.
I know you're very confident in your beliefs, but we always need to re-evaluate them because we can't know everything. Try to remember that everyone has freewill to believe what they want to and they are entitled to their opinions.
