To clarify, there are 4 embarrassing/disgraceful/noteworthy things happening here, which are embarrassing to different people in different ways.

First, the fact that The_Lion thinks this way is a disgrace for The_Lion.

Second the fact that his comment is heavily upvoted is due to the fact that he has sockpuppet accounts which he uses to upvote his posts. It is slightly embarrassing for The_Lion that he chooses to interact with the internet in this way.

Third, the fact that The_Lion has not been banned despite making comments like this one and generating upvotes in violation of the site's policy is a sign of how woefully undermoderated LessWrong is. It is actually worse than it appears from this one example, because The_Lion is the fourth account by a person whose first 3 accounts were banned for similar abuses of the karma system. But after each account is banned, he makes a new account, continues to act in the same ways, and doesn't get banned again for several months.

Fourth, the fact that many people are responding to The_Lion as if this was a serious discussion, despite how transparently false and odious his comments are, and despite (many of) them knowing The_Lion's four-account-long history, shows how badly LessWrong as a community has failed at the virtues behind "don't feed the trolls" and avoiding "someone is wrong on the internet".
