US President Joe Biden has insisted on a ban on assault rifles at a summit against hate crime.
Biden said on Thursday (local time) in the White House in the US capital Washington.
At the same time, he condemned the corrosive effects of hate-fueled violence on democracy and public security.
Hate will always be revived if it only gets enough oxygen, Biden said.
"In recent years, hate has been given far too much oxygen in our politics, in our media and on the internet."
Representatives from politics, business, civil society, the church and the police, who are particularly committed to combating violence, hate crime and radicalization in the USA, were invited to the summit.
"Too much hatred has fueled extremist violence and it's been allowed to spread," Biden said. US intelligence services have identified right-wing extremism as the country's biggest terrorist threat. Biden has repeatedly called for stricter gun laws - Republicans are blocking them However, the plan was repeated again and again: Assault rifles were banned in the USA from 1994 to 2004. Then the ban expired.
Fatal hate crimes continue to occur in the United States.
In May, a racially motivated gunman killed 10 people with an assault rifle in and outside a supermarket in the US city of Buffalo.
The majority of the victims were black.
During a neo-Nazi march in Charlottesville around five years ago, a woman was killed when a right-wing extremist drove his car into a group of counter-demonstrators.
"We must shine the light of truth, justice and justice on this issue and reject those who want us to live in fear of those around us," the victim's mother said during the summit.
