Negative Feedback Thoughts

I have absolutely no issue with anyone sharing their feedback, be it positive or negative. I like to stay on the positive side myself because I enjoy the game. I also don't have it in me to get upset about a game, something that I chose to spend my spare time and money on and am by no means forced to endure. I think both positive and negative feedback are very important and trying to discourage it is not helpful at all.
What I don't appreciate, however, is when people who clearly have no knowledge of their budget and time constraints make personal remarks like that the gurus are "lazy" or "liars" or call a pack "trash" because they don't like it. I guess that has to do with my job because it can happen that people take it personal when I cannot provide them with what they want exactly for reasons that are beyond my control. But I am getting better at not engaging with people on the forums anymore who express their frustrations in this manner.
