Clearly, the ACLU has not caught wind of that. After all, a specifically Christian greeting on a public school (and therefore a government entity) surely violates that non-existent idea of the separation of church and state. It surely pressures everyone who sees it to violate their consciences and convert. Indeed, a Muslim family which were passing by on mere happenstance pulled their car over, sprung from it and ran right up to the greeting. They fell on their knees, making the Sign of the Cross and chanting the Our Father. It had that much impact.
Of course it didn't. No one with a reasonable head on their shoulders would be that affected by a simple wish readily expressed by a small town school. Quite frankly, even if such wishes were expressed everywhere, whether on government property or not, it is highly doubtful that they would impose guilt enough upon someone of another religion or the serious atheist to cause their conversion. The very idea is completely irrational. No one comfortable with who they are would care.
So it leaves us with the conclusion that those who protest against such expressions of faith are uncomfortable with who they are. So uncomfortable in fact that they must deny anyone not of their ilk the right to express their true emotions.
They say that bullies are actually afraid of others and are afraid that they don't measure up to them, and that's why bully. It brings those superior folks down. Likewise, it would appear that the civil libertarians who despise a common expression of Christianity on even government property are bullies. It leads us to believe that they fear their own rightness; they are very afraid that they might be wrong and the Christians the ones in the right.
It surely is a horrid, cowardly existence they must live.
