Last week I became a slightly more visible Humanist when I attached a Happy Human emblem to the back of my car which I had ordered from EvolveFISH.com. I generally prefer that symbol over other secular symbols because it's positive: it doesn't attack religion, it represents what I do believe, and it's actually rather cheerful. With respect to this purchase, I also prefer it because religious bigots are unlikely to recognize it and are therefore less likely to vandalize my personal property. I have heard about someone whose Happy Human had its arms and legs broken off, but I'm sure it's far less common than vandalism to Darwin fish. I haven't received any reaction from it so far and I really don't expect any.
