I have to reply to your comment, since I don't find his comment to be political at all, more pointing to the semantical point of things being illegal. Second, I've browsed through the comments and their submitters comments. I find it striking some people's accounts have been banned on the basis of very few comments.

Lastly, the political debate is often the thing I find interesting about the comment threads on HN, Its getting to see the different viewpoints which interests me. Ofcourse we have to be civil and respectful towards each other, but when we are, I don't see any problem on any topic, how can any topic be destructive to the intended use of the site?
