That said, it is a good example of why the "downvote if you disagree" policy that has been encouraged here is a rather idiotic idea.
Your comment is clearly not commercial spam or anything of that nature. And it does present an argument, with justification for why it may hold true.
It might "offend" thin-skinned people associated with some of the well-established academic institutions you'd listed. That's not a problem with the comment, however, but rather with the people who can't stand to read an argument that they may disagree with badly enough to want to censor.
I don't know if I agree or disagree with what you said, but I do know that it wasn't a waste of my time to read it, and it did get me thinking somewhat. The most bothersome part was dealing with the unnecessarily gray text.
