Kevork Djansezian/Getty Images Producer, director and actor Seth MacFarlane is using his popular Twitter feed to call for a ban on automatic weapons.

Seth MacFarlane has over 10 million followers on Twitter. In the wake of Sunday's Orlando massacre, the worst mass shooting in U.S. history, he’s been using this public platform to take a strong stand against gun violence.

On Sunday, the "Family Guy" creator called for the banning of automatic weapons:

These shootings are a regular occurrence. You don't get to be "shocked" anymore unless you take action to stop them. Ban automatic weapons. — Seth MacFarlane (@SethMacFarlane) June 12, 2016

He subsequently responded to netizens who’d criticized his comment, and again stressed the importance of gun control.

RT @JIMDETHOMAS: @SethMacFarlane should've banned planes after 9/11. // A plane's primary function is not to kill. Get the difference? — Seth MacFarlane (@SethMacFarlane) June 12, 2016

RT @xNathan30x: one person carrying a concealed handgun in that club could have ended that horror. // Often stated, never once happened. — Seth MacFarlane (@SethMacFarlane) June 12, 2016

(2/2) ...is cross-referenced with this data, it's pretty damning. pic.twitter.com/k3MqcfXQtc — Seth MacFarlane (@SethMacFarlane) June 12, 2016

MacFarlane failed to note that the gun used in Sunday's Orlando shooting -- the AR-type assault-style rifle -- wasn't an automatic weapon. It's semiautomatic, which means it fires a single round each time the trigger is pulled. That doesn't mean these weapons shoot slowly, however. Manufacturers have boasted that experienced shooters could fire as many as 45 rounds in a minute.

MacFarlane has not been the only public figure to support gun control measures since the mass shooting. Actress Julianne Moore, tennis legend Billie Jean King, singer Cher and comedian Chris Rock are among the many celebrities who have demanded change.

50 people rapidly killed by 1 AR-15 in #Orlando - b/c in America, maniacs still have a God-given right to not have to reload mid-massacre. — John Fugelsang (@JohnFugelsang) June 12, 2016
