You are absolutely right - thanks for pointing this out, I probably would have gone on making the same mistake for years otherwise.
Three comma splices in two paragraphs? Good Lord.
Two days ago I was very tired. My grammar (particularly written) goes to shit at that point. If you're trying to nitpick someone who was nitpicking, I anticpated that so I rarely make these sorts of comments. I've just noticed a trend of "systematic" being used for "systemic", even though they have very different meanings. It confuses the discussion when vocabulary is used incorrectly like this.
To discuss your comment, I didn't feel that the post brought any particular insight to fixing it, but rather was trying to encourage discussion. Sadly this post seems to have been flagged and is now buried on this discussion site. This problem is not one that we have a handle on yet, and discussion/analysis is key to determining why it exists. Of course, we can't discuss forever, at some point organizations and individuals need to act, experiment with different things and rectify the problems they can (and hopefully not shift them to darker corners).
