Here are some common feminist neologisms, and why using them makes you look stupid:
Don't even try "femail" (female comes from the same root as feminism), womanufacture, or "femstruation"!
There are no prefixes "wo-", "hu-"**, or "fe-". If a cow was called a "wobull", or if bovines were called "hubulls" you might have a case.*** Pairs like "(wo)man" and "(fe)male" are purely coincidental (cf. "girl"/"boy") and do not shape anyone's opinion of women or of gender roles in general. Making up words without looking into the etymology of the original, however, makes me think less of you.
Now, I'm not saying you don't have a right to call yourself a "womon"; I have the right to call myself a "rugaflax" if I want to.
I'm just saying, were I to excersize my equal right to call you a moron for doing so, I would be much more justified.
*I know this is just a pun poking at the percieved male-centricity of history. The only problem is that, in most of history, women weren't permitted to do anything important.
**"Human" comes from the same root as "Homo sapiens".
***Interesting note: Many peopleactually use "cow" as gender-neutral like "man" is often used. Is that misandry? No.
EDIT: The etymological origins of the word "feminazi" and its links to Glenn Beck have come to my attention. To apologize for any misunderstanding, here's a webcomic!
