The main difference between Noose and a loop Knot is that the Noose is a loop at the end of a rope in which the knot tightens under load and can be loosened without untying it. A loop knot does not tighten under load. Any third grader can tell the difference, stick your hand in a noose and pull and the noose tightens. Stick your hand in a loop knot and the loop stays the same size, does not tighten.
The fact that Bubba Smollet/Juicy Wallace is still calling this a noose shows that the whole thing is a big lie. Here's a video from 2017 of the Talladega garages, in almost every garage you can see a loop knot tied at the end of the pull down rope.

Bubba has raced at Talladega 5 times since 2018. His Penske crew have been racing there for ages. Drivers are assigned different garage bays every time they race.
"I've been racing all of my life, we've raced out of hundreds of garages that never had garage pulls like that. ... It's a straight up noose." 

Nooses have been used to hang people all over the globe for centuries. Asians, Caucasians, Latins, Blacks have all felt the hangman's knot. Blacks want to claim the noose as their own special symbol of racist hate. Be my guest but at least use actual nooses when you claim to be victims.
A loop knot is not "fashioned like a noose" and does not function like a noose. You can test the difference in 5 seconds. Bubba and crew have seen these loop knot pull downs before. This was just an opportune time for a hate crime hoax.
Here's a video of this hero, looks like a racist hate crime to me.
