When Donald Trump announced he was running for president in 2015, he launched into a disgusting rant about undocumented immigrants from Mexico, accusing them of the most heinous behaviors.
"They are not our friend, believe me," he said. "They're bringing drugs. They're bringing crime. They're rapists. And some, I assume, are good people."
Trump's speech was a powerful and disturbing example of the undying myth that immigrants commit more crime than native-born Americans. This belief helps people rationalize their racist attitudes and gives them a reason to scapegoat immigrant communities for a variety of social ills.
