I have been an atheist for over 25 years. I have been open about my lack of beliefs that entire time, but not always particularly outspoken about it. I haven't attended meetings or conventions on the subject, haven't worn T-shirts, crossed out "In God We Trust" on my money or done any other even mildly activist atheist things really. (Though I'm seriously considering doing something graphically and publicly damaging to the thinly disguised Jews for Jesus missionary book I received unsolicited in the mail today).
I am also black - actually mixed black/white race - which puts me apart from the predominantly white face of mainstream atheism. I'm aware of the rarity of publicly outspoken black atheists. I particularly felt uncomfortable while watching the Summer Olympics, when I saw many black athletes at the track and field events pray to God before their races and publicly thank God afterward when they won. One woman actually pulled an image of the Virgin Mary out from her shirt and shoved it in front of the cameras after winning her race. (I admit that as I watched track and field and gymnastics almost exclusively, I cannot say whether many white athletes from other events also made such public displays of religion.)
I am also a bisexual female, which puts me apart from the predominantly male face of mainstream atheism. Of course I am deeply troubled by the horrible sexist harassment Greta and others have endured on their blogs. These comments are not acceptable from anyone, believer or not.
As I've written before about gender, I just basically want it to disappear. That isn't going to happen, but I have the freedom to comport myself in as androgynous a way as possible, which is how I'm trending at the moment. I don't consider myself either feminist or anti-feminist, I just think that everyone needs to be treated with equal respect, and it's sad that even has to be said.
As far as social justice, I'm continuing to volunteer with Food Not Bombs, The Free Farm, and The Free Farm Stand, and we give food to everyone, regardless of gender, race, sexual identity, religious persuasion, or even income level. If someone came up to me at UN Plaza wearing a three-piece suit and carrying an expensive briefcase I would still give them the same cup of soup as anyone else. My new mission in life is to feed the hungry, as I've decided that basic food should be a human right, and I'm doing this totally independent of any religious or lack of religious affiliation.
I realize the need for those who think atheism is inherently immoral to see atheists doing good acts, however. On the Free Rice site, which donates rice to the hungry, I joined the "atheists giving aid" group, which is currently ranking at the top of the list. But when one of the people at Wednesday's Food Not Bombs serving asked if we were with a church, I explained that we were not affiliated with any religious organization, but stopped short of saying that I was an atheist. It just didn't seem relevant or necessary, especially as it only referred to me, not our group as a whole. Like polyamory, I will identify as poly and explain what that means to anyone who asks, but I don't go out of my way to advertise it.
The Jews for Jesus book I got today though made me angry, and made me think maybe I should be more activist and vocal about atheism. Giving out free food is still my top priority though. It will be interesting to see what concrete steps this "Atheism Plus" movement comes up with to foster social justice within atheism.
