I think you should read DHHs recent non-technical blog posts (highlights like "As I remember London") and make your own mind up about that. Me and a lot of other people on the internet want nothing to do with it.
So let’s work off of that - expecting the entire internet to read the personal blogs of open source contributors before deciding which packages or modules to run is…not really a solution to the problem you’re putting forward.
Is it white-supremecist code because of distasteful comments in the community, in the code, something specifically written in the codebase?
Or because the author is who they are?
