ASLana, sent you a PM, gong to answer!?
They know not of what they speak! If you totaled up the $$$$ that the Greek Orgs do for Charity, let alone, each schools Greeks, it totals BILLIONS! That is just a year! Add to that the hours spent on campus activities, Da!
People who do not know, throw stones. They are afraid of the unknown!!
Go figure!
I have talked to many of our new members and they tell me the same thing untill they found out what we as Greeks Really do!
