@mcepl I don't think you understood it at all. The TL;DR of the article is that Lua is a toolbox to be adapted, and that the community favours mechanisms and tools over features. There is zero claims about hate whatsoever.
Regarding to your PR, I think your tone there was not right for someone who is trying to contribute to FOSS (I read the mailing list exchange). You literally patronised and antagonised the maintainer because they didn't want your PR. That is not the way.
