I am similar but I would suggest that you could reframe your post. "I started this post with the intention of... and then realised that... (The idea is not a new one/I was wrong/changed my mind because/the idea doesn't make sense etc)." You could even link back to more informative resources on the topic.

Not everything has to be new or novel. You may add to the discussion and enhance it by writing about what informed your change of heart.
