BLAMING someone else for your problems (or the problems of a group) is weakness. It's throwing out excuses.
This is why women and pansy-assed weak men always blame others for something. They haven't the strength to own the situation. They're just weak as shit, incapable, using pathetic excuses to cover up their own inadequacies and shift all responsibility on to someone else.
TAKING RESPONSIBILITY for your own situations is strength. And I'm not talking about shouldering the blame for someone else either: fuck that noise. You weren't put on this planet to be someone else's punching bag or slave.
