Were leftists always this hateful and vindictive, or has their "news" media made them this way?

Liberal indoctrination started decades ago.  It started with the “loving, peaceful, tolerant” ideal which was used to draw people in, much like cults do.      It’s taken many decades to progress to where we are today.  The media, our educational systems, unions, and other organizations have been used to implement it. Morals, responsibility, and respect for the law and others have been eroded over the years to facilitate the indoctrination and create mind numbed robots willing to do the “dirty work“  required to achieve the ultimate goal.  You can see it in the answers of libs on here, totally clueless to reality, just spewing hate toward the opposition.     I think you will see in the next several decades what the long term goal really is.  Enjoy it.  

They learned if from THIS guy in 2016 mocking Hillary's pneumonia  https://www.youtube.com/watch?v=gT-LfVlTE94

What a hateful question.

Since they started shooting unarmed people in the back ( Portland ) and assassinating police without provocation , it's pretty much " anything goes " these days .

You are talking about your own party. Americans are done with your party. God is done and the Republican Party will pay dearly for their actions.

I learned it from republicans between 2008-2016.
