Hillary supporters accepted Trump's win. So, I guess Trump supporters are a lot more whiny than they portray democrats to be.
Why would anyone care if they accept it or not. A result is a result surely?
Acceptance means they can get more done.
It really doesn't matter what they accept. They didn't accept Obama as their President, but I believe he was our President for eight years. Most of them have yet to figure out it doesn't matter who the President is, their lives still suck and they are still stupid.
