How any woman can make herself instantly unattractive to any thinking man: wear a necklace with a cross.
There are lots of alternatives, for attracting "thinking" potential mates at Evolve Fish, jewelery, hats, shirts, etc. with free thought emblems, such as the Atheist Atom, Darwin Fish, etc: [evolvefish.com]
I don't have any tattoos, but the Humanist Celebrant who performed my daughter's marriage had a "Happy Humanist" tattoo on his arm. I didn't know him prior to the wedding, but he recognized me from the old Spiritual Humanist forum, and called me by my screen name there, and when I was surprised that he knew my secret name, he pulled up his sleeve to reveal his Happy Human!
I rarely go out during the holidays, but when I do, I tend to wear a "Happy Solstice" shirt or one with messages such as "Axial Tilt, the Reason for the Season" and so on.
I rarely meet anyone new, in my small community, but I like to express who I am sometimes!
Unfortunately for me, the vast majority of women in my local online dating pool are religious, and usually strongly so, so they always reject me, even the ones who are only moderately religious, that I am willing to accept and tolerate, because, why should they be open-minded and make it a two-way street of tolerance and open-mindedness, when they have three other men, usually fellow believers, to choose from instead of me, in our local dating pool? I am so screwed in my local area, and even with a larger dating pool of two hours away, because almost always, the women there are not willing to date long distance, even if I am and I am otherwise compatible with them.
Same goes for the men.
Sucks to be me, Betty, because in my local dating pool, the cross on a man is a great selling point, even if it's a phony gesture, because 80% of the single women are believers, so there are very few thinking women for me to pursue, and even then, there are three other guys, on average, for every one of me seeking them. It also seems that women like you, are also the least likely ones to ever use dating sites, at least in my area.
