I can't speak as a Rho Gamma, but this problem was prevalent when I went through recruitment as a PNM. Theta Phi is the newest chapter on campus and when I went through recruitment, it was the first formal recruitment the chapter had done since it was officially chartered. A lot of the girls were calling TPA "the free space" because "they'll take anyone, they need members real bad since they're new".......
[[Obviously that isn't true, TPA recruits based on values just like everyone else, not on numbers]]
I did think it was unfair that a lot of the other PNMs disregarded TPA (and the Rho Gams weren't any help...when I heard girls ask about the quality of the chapter, most of them just said "Well, they
ARE new......") but that's okay because my pledge class was pretty ideal (you know, in my completely biased opinion, anyway
)
