My apologies, from the description and the title (forgetting the "holocaust") it seemed like a denier video. I was on my mobile and could not watch more than a few seconds. It was wrong to call it trash if the content is as you describe.
But for fuck's sake, read/listen to the thing you comment on. Is this how engineers should behave? Do you build a new tool instead of understanding the old one? Do you re-do the library based on functional requirements (which you may or may not have read) instead of understanding and maybe refactoring it?
You made an ass of yourself, with your name, blog and github account searchable via your profile. This was a minor offence. Breathe and do better next time.
No need to be vindictive, he already apologized.
So what if his real identity is tied to his account? Even if that somehow mattered, the fact you're trying to attack him for it while yourself remaining anonymous is hypocritical at best.
