You dont need to speak on behalf of OP to give you a heads up about a common problem with your approach, its pretty universal. Picture it this way, there is list of common problems which make a sensible discussion less likely. Which might be overlooked if you havent heard about it before. For example your sentences being too convoluted or having a bad structure. Another one of those is needlessly escalating a conversation.
That kind of boils down to what the aim of your post is. If its not aimed at having a fruitful engaging conversation that might proof your wrong, then you are either doing it for yourself or to set an atmosphere. Which is where the assumption of a sockpuppet comes from.
Differently put, what good does your post if its not aimed at getting somebody to engage in a meaningful way? And if that is your aim, you might want to take his advice, you generally get better results.
