He edited "feminine" to read "feminist," without saying anything about it, so that people who didn't see the original text will think the person who left a snide comment about it was deranged or something.

I edit public posts all the time without making a record of every typo I fix, but I really think that when you remove something people are already discussing, you might make some mention of it. I am assuming it was just a typo, and that he does not somehow think that 'feminine' and 'feminist' are more or less different words for the same thing.
