The left is intolerant of others opinions, nothing new, same game. Their intent is to shunt down counter apposing opinions with violence, riots, social discourse. Read Saul Alinsky or Bill Ayers for a little insight into organizing and disrupting the opposition. Terrorism has many faces, forms, hats, and has but one objective, to force compliance within their guidelines by silencing and restricting ones freedom of speech.
One must ask, if they are so intelligent, righteous, fair, equitable, and just, why do they have to resort to this method of silencing apposing opinions, what do they have to fear?
