radical disclaimer

[Brent]

I just found this radical disclaimer on a webpage:

"In an effort to disrupt the idea that only men perpetrate abuse, the
pronouns used on this web site and in our literature that refer to
perpetrators are predominantly female. Feel free to imagine the
information using varied gender pronouns, such as he, ze or s/he."

Does this disclaimer come from a "right-wing men's rights" website?
Obviously not, pronoun constructs such as "ze or s/he" are rare to
nonexistent in such circles.

Does it come from a mainstream feminist DV or sexual-assault program
website? Obviously not; they would not want to "disrupt the idea that only men perpetrate abuse".

Who ARE these people? They are: http://www.nwnetwork.org/

Surprising, to say the least.
