I have often seen/heard these two terms in many articles and speeches about Feminism or women's rights issues. I couldn't find them in any online dictionary except for the Oxford Dictionary which describes it as
And Urban Dictionary, which has (second definition):
Is it acceptable to use these alternate spellings in my writings and conversations with natives (educated/uneducated)? Does it sound strange, aggressive, or odd in the modern English language? Is it likely to prejudice the minds of my audience against me? Is it illegal to use it in writings and conversations? Which kinds of danger can threaten me?
That is, are these alternate spellings seen as uneducated? Are they used solely by strongly feminist groups who are looked down upon? Or are these spellings seen more positively?
Now, what is my motivation?
I thought it might prejudice my audiences regardless of their ideas about Feminists, or even an ordinary woman/womyn who likes to avoid sexism at least in her talks and writings. Furthermore, if I wanted to work with a group of people who hate Feminists or these kinds of considerations in language, it would help me to decide about changing my workplace or hiding my ideas!
