What you just did was incredibly stupid and harmful. You just put out a manifesto inside the company arguing that some large fraction of your colleagues are at root not good enough to do their jobs, and that they’re only being kept in their jobs because of some political ideas. And worse than simply thinking these things or saying them in private, you’ve said them in a way that’s tried to legitimize this kind of thing across the company, causing other people to get up and say “wait, is that right?”
Essentially, engineering is all about cooperation, collaboration, and empathy for both your colleagues and your customers. If someone told you that engineering was a field where you could get away with not dealing with people or feelings, then I’m very sorry to tell you that you have been lied to. Solitary work is something that only happens at the most junior levels, and even then it’s only possible because someone senior to you — most likely your manager — has been putting in long hours to build up the social structures in your group that let you focus on code.
