On BJ21, you do not have a right to stike back when attacked.
Please do not respond to an attack by attacking the poster in a reply. When attacked, please call us (858-456-4080) or email us (piyeepress@bj21.com) and identify the post that you interpret as attacking you, and the board on which it appears. We will read the post, and if we agree it is an attack we will delete it. An alternative to calling us or emailing us is to post a response that has as its subject: "personal attack; please delete" or some such; don't waste time putting a message under that subject, because when we delete the offending post we will delete your response too.
I suppose a situation could arise where someone complains about a post attacking him, and I read the post and interpret it as being criticism of an idea rather than an attack on a person. Then I would refuse to delete the post. If we refuse to delete the post you don't like, then feel free to respond to it; but even then please do not respond by attacking the poster.
