As much as Trump is hated and vilified by the Dems, he was correct in condemning the violence from both sides.  It takes 2 to fight, and while most of us are disgusted by the white supremacist ideals and incendiary actions, the protesters that gathered to challenge the white supremacists also contributed to the violence.  
This country will go to the dogs if the Dems continue to be naysayers to every single issue dealing with Trump.  If the Dems are truly there to better this country, they need to put away their differences and look for common ground and attempt to establish an honest working relationship with the GOP, finding areas of agreement that they can build on.  Their diatribes do as much to inflame the violence as Trump's tweets.
