HolyGhost7,
I understand what you mean. Personally, I associated it with the Bible. I take it that you are a Christian and so am I. Before I chose the "road less traveled," I thought about when I heard the gospel and how I thirsted for Christ and His Word as if He was water in a desert. I didn't know much about Him, but I knew enough to want Him in my life.
I'm not putting Sigma above God by any means, but the principle runs parallel to wanting to be a member of Sigma Gamma Rho. Sure, you'll be a little shaky to take the plunge wondering how in the world you're going to feel so strongly about the organization, but you'll know within yourself if you're making the right decision. I can't speak for another chapter, but our chapter speaks to anyone we know... whether they didn't cross, or they chose a different path. We just believe in staying true to ourselves... which is exactly what you have to do as well.
I didn't intend on answering this question (and I probably still didn't) but I didn't want you to feel like you asked "the wrong question." You're doing what we want you to do... research!
*big hug*
