I guess it’s safe to assume fancy cable makers like Synergistic Research and many others are adhering to pre-determined directionality of the wires.
Like people who have been brainwashed, it needs to be deprogrammed, left to rest, and then reprogrammed.
It’s the same as for fuses. Power cords are directional in AC circuits. Come on, guys.
Was wondering...what will be this aft chuckle...
Did not have to wait long...

Would not this equal to forcefully switch it's "gender"?
