Antifa May Be The Biggest Liability For Democrats as they instigate conflict with right wing groups causing the general public to move towards republicans. Not only that but they lose every time they start a conflict.
NYPD has recently made an arrest of one of the Proud Boys involved in the NYC scuffle but they are also seeking 3 Antifa activists as well, it isn't one sided. While the Proud Boys may have made the right look bad the conflict was still started by Antifa.
In almost every instance they lose and only show that the far left will start conflicts and scare people but not be strong enough to actually win.
