Who:  I suggested several days ago that Portland pass an "emergency" ban on the wearing of barclavas, ski masks or any other masks at protest, marches, etc.  I deplore violence and support efforts to suppress it.  

You refer to these thugs as "the liberal left".  There is absolutely nothing "liberal" about them (Liberalism is a political philosophy or worldview founded on ideas of liberty and equality.[1][2][3] Liberals espouse a wide array of views depending on their understanding of these principles, but generally they support ideas and programmes such as freedom of speech, freedom of the press, freedom of religion, free markets, civil rights, democratic societies, secular governments, gender equality, and international cooperation.)  from wikepedia..The worldview and tactics of violence we see from those thugs is the antithesis of liberalism.

As a liberal I condemn violence and intolerance.  Please don't demonize liberalism by associating it with anarchism and violence. Gary Crum
