President Donald Trump’s actions in office are making a lot of people angry. Among these is a group of students from Harvard’s John F. Kennedy School of Government, who have come together to launch a resistance platform, dubbed the “Dumbledore’s Army.”

Officially called the “Resistance School,” its website says that it provides “practical skills for taking back America.” It was started by a group of 11 friends, who like to refer to themselves as “Dumbledore’s Army” -- the group of students in J.K. Rowling’s “Harry Potter” series who unite to form a secret society of resistance against dark magic.

“Republicans now control the Senate, House, and more state legislatures than they have in almost 200 years,” the group wrote on its official website. “Those losses have emboldened the right to launch an all-out attack against our nation’s creed — that all are created equal.”

In response to this, the students launched the Resistance School, which is a four-week online course in fighting back and keeping the “the embers of resistance alive through concrete learning, community engagement, and forward-looking action.”

“We just came together as a group of friends who care about something in common,” Yasmin Radjy, co-founder and a second-year public policy student, told the Boston Globe. “And it just turned into this thing.”

The program is not affiliated with Harvard University but has its share of supporters on and off campus. It encourages community action against injustice and has had around 4,000 groups register for its free workshops, the Globe reported.

“We’ve been reaching out to as many people as we can,” Shanoor Seervai, another co-founder and graduate student, told the publication. “We have also had to again draw on our resources, and a lot of students have jumped on board to volunteer.”

The first online workshop will be conducted Wednesday, with one workshop being held every week for four weeks. The topic for the first week is “How to Communicate our Values in Political Advocacy.”

The group is also garnering a social media presence with its activities on Facebook and Twitter.
