The "Bernie supporter" committed an act of terrorism and murder.

What part of "no right to murder" do you not understand?

Your whataboutism doesn't work.   Let he who is without sin?   Are you actually suggesting it was a sin to support Bernie Sanders for President in 2016?   It's not a sin according to the Constitution.  Seriously, WTF?

You think somehow the extremists and violent protesters in Charlottesville should get a free pass because someone who voted for Bernie Sanders committed an act of terrorism?

Seriously?   You're really going to hang your hat on that?

Let me repeat myself.

There IS NO RIGHT TO MURDER OR ATTACK PEOPLE.
