UPDATE2: This type of mass murder doesn't happen in other "advanced countries". *At least not at this magnitude*. Is this a true statement?

This happens in every country, it usually happens on even greater scales as well.

Now I am willing to be analytical first, so let's analyze his statement of this doesn't happen in advanced countries.....
Venezuela, South Africa, Mexico, Nigeria, India, and Brazil are all higher murder rates than the U.S and if we go below the U.S for count of murders for countries like Russia and China, their rate is 9.2 and 7.7, much higher than America's 4.7.

This is definitely not a true statement. Case in point The Charlie Hebdo murders. I hate it when people conveniently forget the facts so that they may support some agenda that they have. Gun control is not the answer to our problems as a country.

In my opinion the solution lies in parenting, personal responsibility and accountability. The family unit in the USA has become a relic from the past. We are dysfunctional because of our fast food mentality. We expect everything right now and do not want to work hard or work at all to get the things we want or need. The current trend is that we as a society are getting divorced faster than we are getting married. When children are raised in single parent homes they miss out on a lot of learned behaviors and nurturing that two parent families have. (yes I know not all two parent families are great, just like not all single parent families are horrid)

Another thing that is hurting us is the everyone is a winner BS.. This does not do anyone justice. Teaching children that there is no loser creates people that are unsuited to function in a normal society where there are winners and losers on a daily basis. It teaches the child that they do not have to work to get a trophy and makes the child who did work to earn their trophy question why they worked so hard if everyone gets the same thing! Thirty and Forty years ago when a child was doing bad in school the teacher would call in the parents for a conference to discuss the issue with them. The discussion centered on little Johnny or Jane and what they were doing.. Today that conversation is now centered on the teacher. The child is no longer held accountable for his/her actions. I have witnessed countless incidences where I have seen children at a playground being bullied by another child. I always step in and stop the action. I usually take the offending child/children back to their parents and inform them of their child's actions. The response I usually get is "hey, it's just kids being kids". By not punishing their child for the misdeed they are reinforcing the actions.

So lets hold this sick individual accountable for this heinous act, and anyone that assisted him and make an example out of them. Set a standard and hold everyone to that standard.

I will add this... Every situation that presented itself, for the President to unite us or divide us, he chose to divide. Each situation presented and opportunity for him to speak on how far we come and our common strengths, he instead chose to take a partisan position and divide the country along racial lines, class lines, political lines, sexual orientation lines, religious lines. He single handely set back race relations and damaged relations among more groups than any post civil war President. We may never recover from the harm he has inflicted.

In China they use knives to mass murder people, want to ban knives now too. Psycho's will always find a way to kill people, it's not the guns.

False statement. Based on number of guns owned, we have one of the lowest death rates caused by guns anywhere. It's not guns you should focus on, it's why the person wants to kill people. It's about destroying families, removing Christianity from the public square, and making people dependent on the government. We are teaching the wrong social skills and replacing community social skills (which typically provide behavior control) with government largesse.

http://www.huffingtonpost.com/2012/07/20/deadliest-mass-shootings_n_1688820.html Please take a look at this. I remembered reading this article in 2012 and I looked it up for this reply. I think we are isolated. It's not that these and other crimes do not happen it's that we don't pay attention to international news. The tendency is to only pay attention to the things that affect us.

are we not counting the most of Africa or the Middle East? heck even parts of Asia are rough like this.

The world is cruel and dark, which is why so many people suffer around the world. People in this country, who have had very nice and comfortable lives, seem to forget that. Somehow some Americans think this country is like living in the dark ages. The terrible things that happen here are no less terrible because of that, but these people that preach how horrible this country dont know what they are talking about.

"Is this a true statement?"
Well of course not, and any rational and even marginally honest person knows its a lie.
But this is an expected and common tact this administration takes. Say what ever supports the position.. truth means nothing.
If caught, walk it back, say you were misquoted or taken out of context.
