FYI, what I wrote is not an ad hominem argument, and "ad-hominem argument" is not an a.k.a. for "personal attack" (neither of which my comment is, for what it's worth).
All that aside, your comment above, reproduced here, is clearly a personal attack:
> Not only are you surprisingly easily manipulated, apparently, don't you have better things to hack on?
Both lower the tone. Both cause unnecessary battles and derail discussions.
