A "safety pin movement" post-Brexit is poking its head up in solidarity with those Americans who fear they'll be disenfranchised by a Donald Trump presidency.

The movement was launched by an American living in London amid reports of hate crimes in the United Kingdom following that country's vote in July to leave the European Union.

The pin is intended to show that the wearer is a safe person to turn to, and the symbol has gained popularity in the U.S. in the days since Trump's election.

Some people, though, like New York blogger Christopher Keetly, say it's better to show support through action. He is encouraging people not to wear the pins.
