From a Facebook comment on Republican attacks on Obama for apologizing to the Islamic world for the accidental mistreatment of the Koran by US forces:
Message to the Republican Party:
A manly apology is not a weakness. It is a strength. An adult, secure in his position, confident in his masculinity, is not afraid to apologize. This, of course, is also true of an adult woman who is self confident and self-assured. The insecure, the frightened, those lacking in self-respect, these are the ones who are afraid to make a sincere honest, apology when an error has occurred.
As a retired elementary school teacher and principal I am quite familiar with this particular problem. Actually, I think every parent is quite familiar with this particular problem. Every kindergartner needs to learn, if their parents have not already taught them this essential fact, that throwing a temper tantrum, hissing and shrieking, and flatly refusing to apologize to everyone who dares to disagree with you is not actually the way to appear to the world to be a big boy or a big girl. The simple fact is, grown-ups apologize.
It does not hurt them to apologize. It does not weaken them to apologize. It shows that they are polite, self-assured, and secure. It bears repeating, grown-ups apologize. Spoiled little children do not.
