Except the group against Huntress's costume aren't ignoring costumes that are more revealing and less practical, they complain about those other costumes too . And Holly isn't ranting about costumes, she's talking about character resurrections and the responses Catwoman is giving are pertaining to this. And the Huntress costume argument hadn't even started when this was written. Annnnd you're really just twisting this comic around so that agrees with you, even though it makes no sense.
This is a parody of the fans complaining about Holly showing up again when she's supposed to be dead. And Catwoman's trying on silly costumes, possibly in response to fans complaining about her new costume "Not being sexy enough" or the fans complaining about the costume change being arbitrary. Which is really the exact opposite of defending Huntress's "sexy" costume.
