Tech industry in general is suffering the same fate. If your views run counter to what’s trending and work in tech you’re putting your job at risk if you communicate them.
I'm perhaps a little sensitive to this and may have overstated things. The comment in particular I was thinking of has indeed been down voted now.
I do see it in maybe a less overt way in a lot of comments on HN. There are comments in this discussion blaming a lack of social programs in the US for the problem. Things like that. There's nothing wrong with believing that, but the counter arguments don't get much visibility around here.
