I have to say that in the past I have had avatars that have either offended or upset people here and those people came to me directly with their concern and I have nothing but respect to those individuals.
I tend to put a funny avatar, like my moonie guy I have now. I have it because he makes me laugh. But in the past I have removed avatars that have made others uncomfortable because I do not want to upset someone needlessly.
Thats just my two cents.
