answer:They will either assume you’re open minded or you’re gay, depending on the employer. You can always join and opt to leave it off your resume. My feeling is that unless you apply to a very, very liberal organization or a liberal charity event or something gay/feminist related, leave it off. Why? Because you don’t know your employers beliefs and don’t want to put them off to you. You can show your open mindedness in other ways. I was fairly active in the Young Republicans group on campus when I was in college. I went to rallies, anti Obama ones too, and when he got elected in 2008, I cried with the others. Yes, I shed tears. While those are my beliefs and I’ll share them with family and friends, I’m not going to show my political or social support on my resume. What if a liberal saw it? Don’t share more on a resume that what is relevant to that job. Don’t shoot yourself in the foot.
