Former US President Barack Obama has once again called for America’s gun laws to be changed in the aftermath of two deadly mass shootings, while underlining the “racist ideologies” behind many of the attacks which have taken place since he left office.

Taking to Twitter, Obama said he and former First Lady Michelle Obamagrieve with all the families in El Paso and Dayton,” before addressing the fact American lawmakers refuse to wind back access to deadly weaponry.

“First, no other nation on Earth comes close to experiencing the frequency of mass shootings that we do in the United States,” Obama said.

Obama, who tearfully called for action in 2012 after a gunman killed 20 children at a Connecticut primary school, said “No other developed nation tolerates the levels of gun violence that we do.”

But Obama also addressed the growing number of racially motivated attacks, saying there’s a “dangerous trend” of online radicalisation involving people who “see themselves obligated to act violently to preserve white supremacy.”

Not just “install” or “enact” white supremacy, mind you. “Preserve”.

He rounded out the statement with a rebuke of President Donald Trump, whose words and actions have tacitly endorsed white supremacy.

“We should soundly reject language coming out of the mouths of any of our leaders that feeds a climate of fear and hatred or normalizes racial sentiments,” Obama said.

Michelle and I grieve with all the families in El Paso and Dayton who endured these latest mass shootings. Even if details are still emerging, there are a few things we already know to be true.

First, no other nation on Earth comes close to experiencing the frequency of mass shootings that we see in the United States. No other developed nation tolerates the levels of gun violence that we do. Every time this happens, we’re told that tougher gun laws won’t stop all murders; that they won’t stop every deranged individual from getting a weapon and shooting innocent people in public places. But the evidence shows that they can stop some killings. They can save some families from heartbreak. We are not helpless here. And until all of us stand up and insist on holding public officials accountable for changing our gun laws, these tragedies will keep happening.

Second, while the motivations behind these shootings may not yet be fully known, there are indications that the El Paso shooting follows a dangerous trend: troubled individuals who embrace racist ideologies and see themselves obligated to act violently to preserve white supremacy. Like the followers of ISIS and other foreign terrorist organizations, these individuals may act alone, but they’ve been radicalized by white nationalist websites that proliferate on the internet. That means that both law enforcement agencies and internet platforms need to come up with better strategies to reduce the influence of these hate groups.

But just as important, all of us have to send a clarion call and behave with the values of tolerance and diversity that should be the hallmark of our democracy. We should soundly reject language coming out of the mouths of any of our leaders that feeds a climate of fear and hatred or normalizes racist sentiments; leaders who demonize those who don’t look like us, or suggest that other people, including immigrants, threaten our way of life, or refer to other people as sub-human, or imply that America belongs to just one certain type of people. Such language isn’t new – it’s been at the root of most human tragedy throughout history, here in America and around the world. It is at the root of slavery and Jim Crow, the Holocaust, the genocide in Rwanda and ethnic cleansing in the Balkans. It has no place in our politics and our public life. And it’s time for the overwhelming majority of Americans of goodwill, of every race and faith and political party, to say as much – clearly and unequivocally.

Judging by initial reactions, the events of the past few days probably won’t spur US lawmakers to make the drastic changes seen in nations like New Zealand and Australia following mass shootings.

President Trump himself has only offered lukewarm plans to amend gun laws, including a provision to enhance background checks – while tying those same checks to his hardline immigration policies.

Don’t expect this to get better any time soon.
