"But in this case the larger problem is that it's (more or less) a single-purpose account for getting into flamewars about Uber. That's not how this site is supposed to be used."

So a person cannot give opinion in a civil way, and highlight information which was not known to others? It is "mandatory" to talk about multiple topics at HN?

How do you define "flamewars"? Just giving your opinion about a topic, discussing, debating is flamewars? Then one could say the entire world of comments on HN is flamewars, since most comments discuss and debate topics.

I believe arguing your opinion civilly, giving reasons etc, should be okay, regardless of whether you talk of only one topic -- or have a particular opinion on one side of the debate. Most users of the site typically have some view which falls on one side on any debate. But they defend it and give their reasons civilly. Thats the whole point, isnt it?

I have read employee8000's posts and they all seem civil. Except for the one which was changed. But that particular comment was wrong, his other comments on this thread are very civil IMHO.
