Should undergrad fraternity and sorority chapters be abolished?

[AXPAlum]

The idea of abolishing undergraduate chapters would, in effect, destroy the greek system simply. Members join while in college, not while they are alumni. It is true some are initiated here and there as alumni or honorary members, but the majority of brothers/sisters come from the undergraduate chapter. It would, simply, be illogical for any greek organization to want to remove their respective chapters. It just wouldn't make any sense at all. Does anyone have a different opinion?
