Questions About John Brown

[maharba]

Here is what the online site History.com - Black History says,

Tubman collaborated with John Brown in 1858 in planning his raid on Harpers Ferry. The two met in Canada where she told him all she knew of the Underground Railroad in the East. Advising him on the area in which he planned to operate,
she promised to deliver aid from fugitives in the region.

It appears she was complicit in a murder/Treason plot.
If she is placed on US coinage or bank notes ($10 bill)
to say the least, Tubman would be a polarizing figure.
The same folks in the North violently advocating for
Disunion and the destruction of the Constitution. Are
there folks today violently advocating Disunion?
