Wow. Um, not even close.
To be honest, I'm completely baffled by that thought. It's an ASCII text version of a waxing crescent moon / full moon / waning crescent moon.
Like this:
The moon has long been associated with women and this symbol, thusly, is associated with the three aspects of the Goddess: Maid, Mother and Crone. It's a symbol of the Divine Feminine.
There's nothing "dirty" intended, nor was it ever meant to be viewed as some sort of joke or slight. Just a simple way of expressing something that's important personally without having to be political, preachy, pushy or anything else.
I'm sorry that it was concerning people and that it was apparently a source of confusion among posters. I'm not sure what else to say. This whole thing is really throwing me for a loop. I guess I never even remotely saw it as anything other than what it was since I knew what it represented!
