So I hold an opinion and do have substantial intellectual abilities. Does that mean I must be erudite in every post? <-- rhetorical answer because the answer is an assumed "No."
No, you take your own decisions, you don't have to give knowledgeable answers. But it is always a good thing to word your answer while taking in respect the nature of forum you are posting it to.
I think you are being downvoted because none of your posts are reasonable or add to the discussion on HN. For example, you asked if all your posts must be erudite, and you believe that the obvious answer to your question is "no".
Basically, when you can't even answer your own rhetorical questions correctly, then it's pretty much all downhill from there.
