But why is this news?
And what's the point in attacking him?
He has his own opinion and we have our own opinions.
Stephen believes that being famous makes his opinion more valid and important than yours.
The fact that yet another psuedo celebrity has in essence called for the overthrow of a duly elected President is newsworthy. Yes, he has his opinion, but in the past the losers in an election, like the conservatives on this site, accepted their loss and while critical of the newly elected President, didn't scheme for his removal from office.
The election of President Trump has brought out a new kind of politics from the left, where the losers don't accept their loss but go on to wage legal warfare against the winner, and try to subvert the election by questioning the legitimacy of the winner, and attacking them relentlessly.
Stephen King and many other leftist celebrities have joined in that anti-American enterprise. They certainly would not, (and did not) accept similar "opinions" if they had won.
