HN is pretty well known to be a cesspool of terrible far-right ideas. What's more, they're not mocked or booed off but enabled. You don't endear yourself to the general public by doing so.
Everyone with a strong political commitment sees HN as dominated by the opposite politics to their own. This is an illusion. For everyone saying what you're saying, someone else is saying this: https://news.ycombinator.com/item?id=23396632. Both statements are false; it's just a large enough and chaotic enough dataset that you can find examples of anything—and the ones you dislike the most will be the ones you remember the most (https://hn.algolia.com/?dateRange=all&page=0&prefix=true&que...).
For sure terrible comments appear. The false part is to say that they're representative of the community—they're not. Commenters with opposite views notice opposite examples, claim those are the representative ones, and are just as wrong. I've mentioned just one counterexample chosen at random, but could as easily link to 50, and another 50 on your side.
"Far right" according to the far-left echo chamber that is Twitter, perhaps. One should never confuse the people who dominate social media with the general public.
