I think the reason why there was a degree of vitriol is due to the perpetual requests for help from [new member]s, with no pictures or actual description of the error occurring, this coupled with the fact that the information that was needed for this question is easily answered with a quick google search.
If you look back to the OP and the following posts before they decided that we weren't helpful, the requests/suggestions being made were quite friendly and accurate. It was only after the OP threw their hands up in the air and basically said we were not helpful that the "teasing" began.
As a community, I find this one to be the most helpful, but even the nicest folks get worn down after a while.
It is frustrating that there seems to be a lack of people trying to figure basic things out for themselves, and they would rather someone hand the answers to them on a silver platter.
Maybe I'm getting old, but damn.. kids these days.
