It's cliche. "Violence never solves problems." It's also not necessarily true. Violence took out the Nazis, freed the slaves and manages to fix every remote control I've ever owned.

It's our duty as civilized people to explain when and why violence isn't the answer.

There's also a huge difference between the peaceful protests led by Dr. Martin Luther King and the destructive forces ripping and looting through American cities today. Interestingly enough, Dr. King actually affected meaningful change through his work. Using the death of an individual as an excuse to loot, riot, and destroy livelihoods doesn't affect meaningful change. All it does is hurt the very cause you claim to support.

Liberals can't seem to wrap their heads around this concept. It seems that every time liberals set out to "protest," we end up with destruction. Violence is the rule for leftists, not the exception. Here's just 5 liberal protests that turned violent:

1. Detroit riots - the summer of 1967 was one of the most violent in Detroit's history. In five days and nights of "protest," 33 blacks and 10 whites were killed, 1,189 were injured and over 7,200 people were arrested. Approximately 2,500 stores were looted and the total property damage was estimated at about $32 million. Like Baltimore today, Detroit's mayor was a charismatic Democrat named Jerome Cavanagh. Cavanagh had anticipated a run for the Presidency, but as his "model-city" burned, so did any future political aspirations.

2. Occupy Wall Street - from vandalism to people defecating in streets and on vehicles to public masturbation and "rape tents" - the violence of OWS protesters is well documented and you can read the very, very long Occupy Wall Street Rap Sheet here. In the end, they accomplished nothing. Yet another bright idea in a long line from leftist, professional protestors.

3. Woodstock - not your traditional "protest," Woodstock was a reaction to and rejection of all things traditional. The original Woodstock Music and Art Fair took place August 15-17, 1969. It included 80 drug-related arrests and and extreme shortages of food, water, and medical and sanitary facilities. Not to be outdone, the 30 year anniversary in 1999 featured violent mosh pits, multiple cases of sexual assault, ATM lootings, vandalism and fires.

4. Ferguson - gunshots, looting, fires... we all witnessed the horrible events that unfolded in Ferguson after the death of Michael Brown. What we haven't talked about as much is the terrible, lasting effect this senseless violence has had on businesses in the area. Local tax revenue down 6%, insurance claims of $250,000... many small businesses in Ferguson will never re-open. The protestors accomplished nothing other than harm the people who were willingly serving their community in the first place.

5. Baltimore - it's happening again, dominating our news cycle and screaming for attention. The burning, the looting, the rioting. A family lost their son, called for peace, and yet - once again - the lunacy that says "destroying things to get what I want in reaction to something that has absolutely nothing to do with me," is winning the day. Baltimore's Democratic Mayor, Stephanie Rawlings-Blake, catered to this destructive behavior by declaring, “We also gave those who wished to destroy space to do that as well.” Seeing how it's worked out, um, hey... how about giving the whole "not rioting" thing a try?
