Petalsinthewind, as explained by this nonny discussing this ontd_f thread,
is a dude. He often posts about women's issues without disclosing the fact that he is male. Somebody brings this up in the comments of one of his numerous posts about Asian women and other WoC. The mods (mostly entolodont) react in a very faily fashion, bringing up gems like "BUT WHAT ABOUT HIS INTENT?" and "It sucks when white people whitesplain in posts about PoC, but petalsinthewind mansplaining is ~a very complex issue."
This wank made sf_drama and was one factor in Entelodont (see The Femdome) falling from grace among that crowd.
