Is it common for graduate students to rush a fraternity?

[md0816]

I finished undergrad in May, but I seriously regret not ever rushing a fraternity. Honestly, I was scared about the possibility of hazing (not the normal "pick on the new guys" type of behavior but the abusive stuff that appears in the news), and I thought I would have to stay in the closet b/c I believed that all of the fraternities on my campus had anti-gay attitudes (some do but not all). Unfortunately, I realized that I was mistaken when I was already in my senior year.

However, the university where I'm getting my masters degree allows graduate students to rush, so I'm interested. I went to 2 rush events this week, and the group seems really cool. I think I can handle the pledge process if they give me a bid and make the time commitment to be an active member if they decide to make me one. Still, is it a good idea for a grad student to do this? Is it uncommon for grad students to rush? Did any of you rush during grad school?
