It's a scary thing to realize though. No one wants to "be a loser". They don't want to think that had THEY done something differently that the outcome may have been better. They want to blame someone else for their misfortune. Much better to be a victim, than to be a loser, and let's face it, the angry chemicals are way more fun than the depressive ones, and a lot less complicated than doing the work.
I can only assume that people who post these kinds of memes don't really understand human relations. The "you don't deserve me at my best" is even worse. I've known some people at their worst.. and they are the worst. Why on Earth would someone feel that they have every right to be horrible human beings and treat other's badly, but if the person they're treating badly doesn't like it then they're the problem. The quote should be, "If you can't handle me at my worst, I wouldn't blame you if you didn't want me at my best either".
