And also, it's really childish to even bring up karma like that. You were better off citing your 4 years on HN if you needed to validate yourself.
As far as Hollywood killing themselves that's not what he was doing. I quote from his post...
"The people who run it are so mean and so politically connected that they could do a lot of damage to civil liberties and the world economy on the way down"
That's calling them names and assigning motive. Not observing their behavior and pointing out what the probably consequences will be.
The attack wasn't on your friends, it was on a personification of Hollywood. And as a whole it indeed is very old and seemingly dying.
It's not me downvoting you by the way.
As for the downvote I have to say when you go into a topic like this where you know most people are going to be against you the downvotes become a point of pride. Whether people want to admit it here or not Karma is of some value (otherwise why would it be there). Being willing to lose something of value to stand up for what you feel is right actually feels kind of good.
