Interesting, but I'm a bit disappointed the author didn't at least try to filter out things like "grammar nazi" or, as might be found in r/seinfeld, "soup nazi".
I don't think we can draw any conclusions from this beyond the fact that the Reddit hive mind thinks Godwin's law is hilarious and mentions Hitler at every opportunity.
"And in the end anyone who feels like that reminds me of the Nazi's"
"The Nazis did that and you see what happened to them"
"The way he makes comments it's like he's a grammar nazi"
Yes.
