There's no inconsistency there. It doesn't bother me personally, but I find it to be in poor form.
And where is she showing "a regular basis" of noting other posters' genders??
I've seen it on a number of threads now.
I haven't seen it, and I was inviting you to substantiate it (the comment about a pattern of making gender-prismed comments). Maybe it's not worth the effort, probably isn't actually, but your saying you've "seen it on a number of threads now" doesn't really help me there. *shrug*
