There is a very enjoyable irony to the notion that you would accuse a community of groupthink for a perceived lack of accepting your opinion as the one true way.
The only opinion I was expressing was that of surprise the down vote for a perfectly decent comment, it seemed to be related to the topic, rather than the comment. I admit, the group think statement is a hypothesis, but not an unreasonable one given the circumstance.
Seems HN group think favours regressive tax?
