I am not doubting your comment, but personally it did not cross my mind that something is wrong with the syntax or grammar before I read your comment. It is informal, brief and not getting that deep, but it was pretty much understandable for me, and it sets up an interesting point to discuss imo. It could have been more polished but it looks readable enough, and I do not think that a post like this should be flagged (not implying you specifically flagged it or not, either, but it is flagged and I assume some of the reasons for it may be this).
