Fat acceptance movement...

What are your thoughts in the fact acceptance movement? While I believe everyone should respect themselves and have love for themselves, I do not believe in accepting being overweight as a beautiful thing and shaming people who are not attracted to overweight people. Everyone has a type or types as they see attractive and it's not a choice. There is nothing wrong with having a little junk in the trunk but if someones unhealthy and can't spend time running around with their kids then I do believe that they should get motivated to make some changes instead of accepting themselves for who they are and getting all upset if other people don't. I know that sounds bad but I'm not sure how else to word it. What are your thoughts?
