The true liberals need to reclaim the label by rejecting the violent bullies and totalitarian SJWs.
The press needs to stop engaging in automatically assigning labels of stupid, crazy, -phobic, evil to conservatives - as do professors, late night comedy news shows, etc. Even CBS admitted that was part of the problem.
The unbearable smugness of the press
Recognize that many of the grievances that led people to support Trump are valid problems that need to be solved, and that socialism cannot be the default solution.
When communities say "we can't take care of our own unemployed we can't take in Muslim refugees", don't immediately call them Islamophobic.
When communities say "vets are dying for lack of care, giving illegal immigrants under DACA free housing, clothing, medical care is wrong", don't reflexively call them racist.
When populations with high unemployment say we need to close the borders because illegal and legal immigrants are depressing wages and displacing Americans in the workforce (most new jobs in the past 10 years went to immigrants, pushing Americans onto SSDI and retirement), don't rush to scream "racist".
When people point out that it is an insane double standard for Muslim truck drivers to refuse to drive a beer truck or Muslim taxi drivers decline someone with duty free wine but someone says I don't want to make a blasphemous wedding cake, don't immediately insult the person only in the second case.
The left labeling themselves good, love, smart, & rational allowed them to label conservatives all sorts of insults. It was an excuse to ignore the other side's views and delegitimize them to others - but when people can't talk things out, they only have action.
Thank god we had an election, because if that hadn't been an option, there was a good chance of violence.
But for the political left, there is no justification for the instigated violence they committed at conservative events to blame on conservatives (Wikileaks, Project Veritas revelations), nor these organized riots planned by various liberal groups like MoveOn. You had power for eight years, and you've had an election. You had peaceful options, and so did we.
We won't have peace until liberals give up their "good" branding and renounce the violence they took up to "fight evil", the other political wing.
