Please don't take this personally, I understand the point you're making in relation to the parent, but your comment reminds me of one of my least favorite aspects of HN: Comments that contribute nothing to the discussion and only observe that another comment employs some logical fallacy that they stumbled upon on Wikipedia last week.

Read any recent thread on Facebook's move to censor white supremacy and you'll see dozens of "That's a slippery slope fallacy!!! [0] [0] https://en.wikipedia.org/wiki/Slippery_slope" without actually addressing the argument or how the fallacy even fits. It reminds me of high school debate team.
