You can color it any way you want, but Delta pilots "selling out" is really no different than pilots joining a lower paid airline to get their foot in the door or paying for your job via a type rating. (you can deny pft all you want, but we all know what is going on)
Chastising Delta pilots collective behavior, while defending yours makes you a hypocrite. Individual choices are much easier to make, and control. Trying to get 14K pilots to turn down a 21% raise is much more difficult.
BTW, I am not knocking you for taking care of your family. There are much more important things in life than flying airplanes. People will find ways to take care of themselves, especially in this business. Some fly maximum, some sue, some scab, some call in sick to do their "other job", some cheat, some just do their jobs and go home. There is no such thing as a "collective group" anymore. Those days died long ago.
I could go on an on about the SWA pilot group, and how they continuously screw the entire piloting profession. You could make a case that everyone is working more, making less, and lacking retirement due to SWA pilots hanging on the bar since their inception, but then IO become you. Griping about not getting your love, how your pilot group screwed you, how the Delta pilots screwed you, and everything else just makes you a hypocrite. I will give you credit, your story is unique--just like everyone else's.
