Greek Life and Religion? Open to All current Greeks ?

I recently came across this video on you tube by an ex member of Sigma Gamma Rho, claiming that the organization is demonic.

How has being a greek affected your religion? Does your organization worship Roman and Greek gods? Does your chapter still haze? What is your response to the video?

Thanks.
