Everything I ever learned about making a hanging noose, I learned in a college dorm in the 60s. I went to a university in Northern Minnesota. A student in one of the dorms proudly made a hanging noose and showed it everyone near by. It took learning and skill to make a proper noose. It needed 13 loops, and a particular knot to allow it to slip, but not fall apart.
There was absolutely NO racism involved. Hanging was still a method of execution in some states, and a proper noose was required. No one I ever knew at the time thought of anything racial about it at all.
Heck, the bad guys were hanged in all sorts of Westerns in that era. White bad guys. I remember learning to make a noose as a 10 or so year old. Because good guys knew how to deal with bad guys, and we wanted to be good guys.
