I spent years on that subreddit and never once saw somebody that identified as a Nazi calling for the deaths of Jewish people. I bet you can't find any such examples. Your viewpoints of the world are based on hearsay and propaganda, not facts and logic.
Which subreddit? /r/the_donald? I was talking about the site in general, which did have explicit hate subreddits, which Reddit started struggling to grapple with back in 2015. I do find it kinda funny though that you saw an accusation of antisemitism and immediately started defending /r/the_donald.
It is worth noting that I did see explicit and implicit (((antisemitism) on /r/the_donald, but also, no examples are possible anymore, as the subreddit is gone /shrug
Perhaps not literally, however the subreddits namesake literally retweeted a video of someone exclaiming 'white power'. Most people who are not facists and are not nazis wouldnt exclaim something like this and would not support someone who retweets such things.
I'm not sure I see where the joke is - this was inevitable.
