No one is against Python developers, you're clearly exaggerating, I would ask for a source but we both know it doesn't exist. What people try to convey the whole time to people coming from python, which I was years ago, is that nim is not compiled python. It's a totally different language. I am sorry that message sometimes gets lost in translation but I don't know what would be clearer than this recent thread.
