Streep's comments on our new president were restrained and to the point, relevant mainly to the phenomenon surrounding his irresponsible and often untrue statements, and his attacks on weaker members of society from a position of power; in other words lying and bullying.  She's just pointing out that it sets a bad example when performed by a president, or any leader, and so it does.  

Of course, in return she gets attacked, demonstrating her point.  I think it'd be newsworthy to know if she's gotten any death-threats from the chorus over this. 

Trump's going to have to grow up, or waste a bunch of the public's time on Twitter making counter-attacks, and weakening his Office and the Republic with every spiteful word.
