I re read your article, and it appears I took information from your headline and assumed it into your examples. I think you're talking about plain vanilla market making and speculation. Nothing in there is what I would consider predatory or HFT or front running. These things exist, per my best reading of the wsj, and you said you were defending HFT but as best I can tell merely defended computerized market making and speculation.

The thing that is being called "front running" here involves multiple exchanges. There is no cutting in any single line. There is more then one line, and you can be in multiple simultaneously. In some cases, traders may go through one line and then complain that HFT traders went and got in the other line. In order to call that "cutting in line" and be well founded, you need to come up with some framework for how that "line" works - it does not fall trivially out of the actual lines in the two exchanges.
