>Roads are neutral, social networks are not.

The gp's analogy maps better this way:

  roads = ip packet network routing, DNS, telecommunications cabling
  racist conventions/meetups = social media platforms like Facebook

Therefore, "I hate the internet" is analogous to "I hate the roads" because their perspective is dominated by seeing all the racists meetups that use the roads.

(Yes, people do "hate traffic" but that not's the same as "hating roads". Anyone who has travelled on unpaved dirt roads or gravel trails that make their teeth rattle will appreciate having paved roads. And that appreciation doesn't change even if a lot of KKK racist members also use roads.)
