Of course this is all open to interpretation, but in the way we interpret the site guidelines for moderation purposes, "You are trying really hard to obfuscate the issues here" is crossing into personal attack. Note that phrase "crossing into"—it's meant to imply an errant elbow rather than charging at someone. Both are penalties but the latter is worse.
Please see https://news.ycombinator.com/newsguidelines.html and note this bit: "Please respond to the strongest plausible interpretation of what someone says, not a weaker one that's easier to criticize. Assume good faith."
