If anything you have it backwards. The first part is fairly tame, maybe even admirable to some. The latter part, whether true or not, is easily seen as inflammatory, etc. Not to mention that if he is as bad as you think he is then all you are doing is boosting his ego -- and to your detriment no less!!
You say there is nothing you can do about it, but you're like an American football coach who keeps calling the same play over and over again and then wondering why your team lost. The conclusion is obvious -- if you want to do something about the situation then you need to change your approach. As an example, do you really think the rest of us care about your inflammatory sock-puppet diatribe? Try leaving inflammatory comments like that out next time and see where things go.
