Did I say she wasn't allowed to post her suggestion? No. But when you post your suggestions on a public forum you are opening yourself up to critiques and criticisms of your idea. Last time I checked, everyone wasn't required to agree with people on the forums. I criticized this suggestion because it is based solely on gender, a basis I find it abhorrent to make classifications based on. Guess I'm not entitled to *my* opinion or to be offended at the suggestion that the game that I've played for the last 5 years needs to be changed to accommodate my gender. Sure, I have made suggestions about being able to dye my WF pink (and got mad when they got rid of pink docents) but that's no different that requesting armor kits and certainly doesn't affect fundamental game balance or mechanics.
If she changed her mind halfway through her post, there are means to edit what you have previously typed (i.e. backspace or "edit" if you already clicked "post"). Either way, she wanted a game mechanic changed because she didn't like the way something looked. It doesn't matter what the Eberron history is of it. I wouldn't have even clicked on a post suggesting different body types for WF. But, I did click on a post entitled "petition for an arcane healing spell for women".
