I myself am a Roman Catholic, but I am also an Ancient Historian, so I look into the history of wars and religion in more detail than some of you may do.
The fact is, as some of you have stated, wars are started due to religion; however to say this is the end of the matter is silly. From the time before the crusades, Religion was used as a tool to control the masses. This is not the religion we know today; this was rife with corruption. Men would use there positions ot amass wealth, power or use it as a stepping stone onto bigger and better tings; the fact is wars were not fought merely due to religion, it was these men that made the people think it was a war of religious issues.
The popes and clergy we know today are far from the men who controled religion way back when. These men you would see fighting in battle, some of the best warriors as well. They were far from pious as you may think they were, and cared more about themselves and their assets than the word of god.
Men would join the crusades to gain religious office, which inturn would create income for themselves, so it is foolish to think that all of this was down to just religion. The greed of man was at work here

Oh and just so you know, the rabbit is a symbol of spring, the egg is a symbol of new life.
Moreso, opening the egg and finding a surprise inside (chocolate or toys) is a representation of the disciples finding a surprise in jesus' tomb; this being that the mofo wasn't there!
