There is quite a lot of evidence that Dutch has many socks, including evince, Nordberg, Lefty, BidenPresident, and of course, a Sybil (probably an account on another forum? An imaginary person?). He has also gone by the name of Swan.
I don't think he's Flash, though. Flash is just a stupid believer of Dutch.
If you go by Dutch's definition of what is a sock, which is that they sound the same, then they are all socks of Dutch...including Flash.
They all use psychoquackery. They all hallucinate about things that aren't there, things that people have said or done, etc. They all tend to use inversions (projecting their own problem on others) in the same way and extensively. They all deny science, mathematics, history, and the Constitution of the United States in the same way. They all hate America and claim to be 'patriots' in the same way. They all blame others for being socks in the same way.
Having said this, let's return to the thread.
