When you've been saying the same thing for the last 40 years, and seeing the same responses, more often than not made by people who don't understand where this all comes from, and which do not really counter what you're saying, you'd be rude and dismissive - especially whith the dogma that surronds the "UNIX philosophy", which, in case you aren't aware, wasn't actually put forward by anyone heavily involved with UNIX development. Some empathy with the protagonist whould help.
I once got a mail back from dang, about why my account got restricted. (Limited posts per day)
"I made plenty of good comments, but this one thread counts as flame war and he has to go by the worst, not by the best comments"
I thought about replying with some Don Hopkins comments, that were way worse than what was here and he is clearly not restricted. But I didn't, as I don't do Kindergarten, I just took a time off from HN.
But it definitely is not equal standards.
So I respect Don Hopkins for his knowledge and experience, but not his style of communication sometimes.
