Well, this is a forum that is open to many people with different opinions of what matters and what doesn't, and most importantly, with a number of people who find themselves, probably for the first time in their lives, questioning what they have been taught for their entire lives. So it makes sense that to some people those kinds of posts feel relevant and important.
Not everyone has the ability, capacity or emotional intelligence to articulate things or to talk about things in one given particular way or with the depth of thought that some may find compelling. And not everybody is interested in posting about the same subject or from the same perspective.
In other words, if you don't like it, simply ignore it and move on. People are free to post what they feel is valuable to them and there's nothing wrong with any of it for as long as they abide the forum rules.
