If any of you follow gun content on YouTube, you're probably aware of the late Ernest Barry Elliot of Iraqveteran8888.

Fuck him. He was a racist and a sexist. He knew borderline nothing about the subjects he talked about, and spread lots of racist disinformation.

His famous "grab your crotch and hold the gun sideways" scene is a perfect example. Machine pistols become a fair bit more controllable when held at a 45 degree angle (see any hickok45 video about a machine pistol). Due to the huge dump of cheap machine pistols into american inner cities in the 80s, this became a fixture of rap videos (usually with a MAC 11) and therefore became "wrong" in the eyes of our terminally white boomer.

Beyond that, most of his info on cartridge selection and accessories is just straight up wrong.
