It seems like a standard practice on HN nowadays. I am afraid some mods may be politically charged. See the following thread for example https://news.ycombinator.com/item?id=42716926
dang is about as politically neutral as it gets, but it's become very apparent that anything that points to something negative that may loosely relate to Conservatives or the Republican party will get flagged by users.
Sad to see it getting flagged here, especially given the context of my post. I do appreciate that it got shared here and all the comments so far. I put a lot of work into this and I really appreciate that people are sharing it around.
