A gay college senior asks: Will coming out on my resume hurt my job chances?

Dear Civilities: I'm a gay college senior who is comfortably out on campus. Now that I'm looking for a job, I'm wondering if I should mention it on my resume, allude to it in a cover letter, or bring it up in an interview. I don't want to closet myself again, or lead a double life, but I'm also afraid that being too "out" could hurt my chances in the job market. What do you recommend? If I should come out, how do I do that without showing up in a "LOVE=LOVE t-shirt?" -Name withheld, Durham, N.C.
