Is there a link to the actual comment made by Chu?

Yes.

This is class bias though. Some people are not in a position to create and live in a walled garden, either in real life or on the internet, especially in places without an internet connection.

Sucks to be them. You seem to be arguing something I've seen elsewhere, and which for the sake of definiteness I'll state in the strongest form.

No-one ever achieves anything through their own efforts. All "success" is due to privilege, which is oppression. So-called self-help is privilege used as an excuse to blame the unprivileged for their situation, which situation is in reality due to oppression by the privileged. Showing people what they can do for themselves is disempowerment. Blaming their troubles on the forces of privilege is empowerment. Individual action is vice. Collective action is virtue.

Do your thoughts point in that direction?

I've put a lot of thought into the politics of anger and I see value and problems on both sides. Arthur Chu appears to have expressed a much more intense version than I've seen in say, Feministe or Atheism+. Although one Feministe commentator expressed her belief that she would be morally correct to murder or burn down the house of people doing things which don't justify such a response in my personal opinion.

"A lot of thought" is not a phrase that leaps to my mind on reading that. Does any of this seeing value and problems, and having personal beliefs and opinions lead to anything but more words on blogs? I'm glad you don't think murder and arson should be freely employed, but what does it mean to say that judgement is your personal opinion? That it doesn't matter?
