Do colleges and employers support gay rights?

I personally am straight. However, I don’t think being gay, having an interracial partner, age difference, etc. should even be an issue. I was actually really appalled when I stepped back and looked at the society we lived in. Like the interracial Cheerios commercial controversy. Are you kidding me? Anyways, at my high school they recently created a Gay Straight Alliance Club. I’m planning on joining it and I was just wondering what colleges and future employers would think about this? If I put this on my résumé what do you think the effect would be? Just wondering. Do colleges and employers think of this as a plus because I’m “open-minded” or whatever? I don’t know. All answers welcomed.
