As the corp's name mentioned: We are all together in this corp. It may not last forever but as long as you stay in the corp "together us" is the main spirit.
However, it's nothing like we holding hands flying around EVE. We are fighting, having fun, making jokes and trolling each other, we protecting and standing by each other so all of us will be together as one.
We are always welcome to those who treasue long-term friendship.
