In general (since that's what you said you wanted to focus on), questions on Stack Exchange are not supposed express specific beliefs, opinions or points of view. Rather, questions are supposed to ask for facts or, in some cases, opinions. This is generally best done using a clear, neutral tone that simply asks the question without any unnecessary digressions or asides.
To quote the help center page on "What types of questions should I avoid asking?" (which is the same on all SE sites, but I linked to the skeptics.SE copy since that's where you seem to be most active):
If your motivation for asking the question is “I would like to participate in a discussion about __”, then you should not be asking here. However, if your motivation is “I would like others to explain __ to me”, then you are probably OK. (Discussions are of course welcome in our real time web chat.)
To prevent your question from being flagged and possibly removed, avoid asking subjective questions where …
- your answer is provided along with the question, and you expect more answers: “I use __ for __, what do you use?”
- there is no actual problem to be solved: “I’m curious if other people feel like I do.”
- your question is just a rant in disguise: “__ sucks, am I right?
If you feel that you might be able to provide an answer to your own question, you are, of course, welcome to do so. Answers may, and indeed should, express the answerer's opinions and beliefs on the matter, at least as long as those opinions can be backed up by facts and references as required by site policy.
