Funnily enough, that seems to be a common reason to suppress discussion of many issues of rights and fairness, whether its been about same-sex marriage or sufferage.
And people get called jerks in those discussions, too.
This isn't the "start" of the cause - this cause and problem has been going on for literally years now. Perhaps you are only just becoming aware of this because of this HN thread, but a lot of people have been fighting this for a long time.
It seems like you think people don't have a right to be angry about this problem. I think that shows how much you really care about how it hurts people.
