There are some knee-jerk reactions to the seemingly "political correctness run amok" move to put Harriet Tubman on the $20 bill, replacing President Andrew Jackson. But the replacing of the slave-owning founder of the Democratic Party with a gun-toting black Republican may spark a political debate worth having and unearth historical truths worth learning. As PJ Media described the announcement:

The first woman on United States bank notes will be the famous abolitionist and Republican Harriet Tubman, Politico reported Wednesday. She will give the boot to the nation's sixth president and a major figure in the Democratic Party, Andrew Jackson, on the $20 bill, and save the founder of the nation's financial system, Alexander Hamilton, from being kicked off the $10 bill.

Biographer Kate Clifford Larson notes that Harriet Tubman was no stranger to firearms, finding them a way to protect and reassure slaves she shepherded to freedom in the North, perhaps making her a founder of the “black lives matter” movement:

Harriet Tubman carried a small pistol with her on her rescue missions, mostly for protection from slave catchers, but also to encourage weak-hearted runaways from turning back and risking the safety of the rest of the group. Tubman carried a sharp-shooters rifle during the Civil War.
