It's possibly because your original downvoted comment was a vague hit out at 'the man' castigating the establishment and placing this trader in the same bracket as Madoff.

It had no facts, no real argument, was unspecific, ad hominem and didn't advance the debate in any particular direction that was useful or informative.

Much like your second comment.

You could have pointed, for example, to the rise of HFT, and perhaps asked why this particular trader was being penalised unlike several larger HFT operations when he was front-running or pulling trades before they could be completed. (See Flash Boys by Michael Lewis). Then, chances are you might have been upvoted.

We can take dissonance. We just prefer it to be informative.
