You seem to really like to tell people that they don't know what they're talking about more than you seem to be parsing what they're actually saying.
I remember when I used to look for reasons to pounce on people for not knowing what they were talking about based on a superficial thing or two rather than try to understand what they were saying. I mostly got past it as a teenager, though.
There's not really a point in talking back to abuse. Think what you will.
I will point out that your comment was the first reply ever to someone completely new to HN, though.
