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.
