Lastly, we do recommend that new contributors (posters or commenters) take time to familiarize themselves with the sites norms and culture to maximize the chances that your contributions are well-received.

While we should be polite, we should not have to submit to a culture in order to produce submissions.  In other words, aligning with "norms and culture" will normally produce bias.  We should not care about how "well-received" something is, rather, we should just be concerned with how right it is : )
