I thought your previous post was sarcasm because of how absurd it was, but I guess it wasn't.
You do have to accept him as President because he's going to be the President. That isn't going away. Come January, he'll be in the White House. You can disagree with him and dislike him, but saying that you're not going to take the results of an election is pretty outrageous.
The lack of introspection from the left irks me a lot. Like maybe, just maybe, the Democratic Party made a lot of mistakes that led to its embarassment on election day and it's time to fix those mistakes. That's way more productive than throwing the NotMyPresident hashtag everywhere you go...
