You're saying a "nice" person should stretch out a hand to help anyone, even someone who you deem as undeserving of such help. Furthermore, you take this one indication and immediately extrapolate from it that the other people who posted in your thread are "mean" (understatement yes I know).
If that is what you define as "nice" then I could make the same assumption about you as being "incompetent".
I would be extrapolating from the fact that you somehow did not read any of the stickied threads or the several threads with SMP on them at the top of your screen but instead chose to immediately ask for help with the new thread option about an inch or two away from said threads. I can probably infer from this that your observational skills are sub par or you can't put two and two together and come up with the above incompetent conclusion. Maybe both.
I'm not saying you are, just trying to make a point that you shouldn't draw such conclusions especially with the high post count of the people who have posted in here. Yes believe it or not, these "douchebags" are some of the most active advice givers in this section of the forum.
Last thing, as for the "bend backwards" you technically are asking them to do so. This is an internet forum. You asked them for help and they have 2 options, post or not post. To post advice and help in your situation is the one that takes effort out of the 2 and it would purely be on your behalf and not theirs so they would be going out of their way to help you no? If that isn't bending backwards by taking the time to post for an online forum, then what is?
