🧠 These people are stupid!
Glowfag is someone who suggests violence is the solution, instead of waiting for law and justice to prevail. They're considered to be FBI agents trying to incite/honeytrap others to go along with their bad intent. They "glow" because everyone can see them for what they are.
Frens is what retarded pepe would say. Retarded pepe is a meme that represents a newbie who is still learning (or whatever else you want him to mean to you). Retarded pepe is cool enough that people would still emulate him, even if they are well learned. You either get it or you don't. Those who don't are usually liberal, because liberals are incapable understanding memes.
Pede comes from an early meme about Trump https://www.youtube.com/watch?v=MKH6PAoUuD0 taken from a national geographic documentary about centipedes being "nimble navigators". Pede is more of a Trump meme than a Q meme, many Trump supporting communities call themselves pedes without reference to Q.
Most of the other explanations you gave sound about right.
From Knife Party, not a documentary:

Correction : The nickname pede, short for centipede, for Trump supporters, came from Can't Stump the Trump videos made during the 2015/16 presidential debates.
In the popular videos, Trump was called a lethal predator and "nimble navigator" which referenced the National Geographic documentary's description of centipedes. Clips from the centipede documentary were part of the intro to each CSTT video.
AFTER choosing to link Trump to the lethal and nimble predator, the centipede, the Can't Stump the Trump video creator chose music from Knife Party to underscore the centipede reference.
