I don't think that you're accurately representing the state of affairs.
At the time I'm reading it, your second comment (http://news.ycombinator.com/item?id=1799442) is neutral at 1 point. That is not a symptom of people acting "toxic" and trying to "discourage" you. It was a good question, but nobody seemed to know much about it, so it just sort of sat there.
Your first comment (http://news.ycombinator.com/item?id=1787833) is at -3 points. Unfortunately, as it's five days old, I can no longer put it at -4. You stepped into an admittedly poor discussion about specific reasons why SO might need less servers than Digg, and posted a flamebaity generalization with absolutely no support; you didn't suggest a reason that .NET might be faster than LAMP, nor any evidence that it might be faster, or what it might be faster at. You just dropped a one-line load of an opinion and left. I absolutely am on board with being maximally toxic and discouraging toward the comment you made there.
The 2nd comment (http://news.ycombinator.com/item?id=1799442) was downvoted. I saw it after I posted it. It was brought back up by others upto 1 later. Tried as I might I just couldn't understand the rational of the downvotes. I could only attribute it to the Reddit-like behavior where every submission has 33% downvotes, which is why I'm saying HN is heading the Reddit way.
For the first comment, it's pretty well-known that C#/VB.Net is way faster than PHP/Python/Ruby in raw performance. Benchmarks after benchmarks have shown that fact. Often it's just a matter of bringing it up as a reference in discussion. I don't want to prepare a benchmark for every statement I made.
I've seen plenty of opinionated single liners got plenty of upvotes, admittedly those stated the popular views, so single liner is not a good reason for downvote. But nevertheless I'm not into a popular contest. If HN can't tolerate diverge view/opinion, that's its loss.
