If being asked to get an avatar multiple times rankles your feathers THAT much that you are threatening to leave over it, then yeah you're probably too thin skinned for this place.
My feeling is, so be it if that's the case. I feel like we are welcoming to new members, but this place has existed in various forms for 12 years now with mostly the same core members so a new member can't expect the tenor of the board to change to fit his sensibilities.
This forum has always prided itself on open, honest, raw, intelligent and unfettered posting without worrying about walking on eggshells.
An avatar is an easy shorthand for recognizing who you are talking to, and it's courteous to use one. If no one had an avatar it would be like dogs and cats living together mass hysteria.
