You probably don't care if you can convince tptacek, but to random people following along (who you might be able to convince), calling tptacek mindless undermines your goal.
I'm not really concerned. I mostly post comments because I have all these thoughts in my head and I want to let them out.
I called him "mindless CISPA defender" because based on his comments on the subject, that seems like an accurate description.
And in my specific case he seemed to pay no attention whatsoever to what I brought up and replied with a handful of boilerplate responses that didn't really apply to what I was saying. So, that seemed pretty much like a mindless automaton to me.
