Femi-Nazi is a term of abuse used by right-wing journalists in America to put a darker hue on feminist activists.
Like many terms of abuse it's been taken up as a badge of honour.
Once upon a time if Yahoo didn't like my groups they deleted them.
Then if they didn't delete them, they consigned them to the adult category where they cannot be found by search engine.
Then if they didn't do that, they stopping listing them in the group charts and consigned them to a jumbled space at the back of the listed groups where no-one is going to bother to look.
So when they did that I changed the group name to include the phase Femi-Nazis.
After that Yahoo stopped listing groups in group charts so they are all jumbled up in no particular order.
