I agree that change takes change, but I also think the three million other available crossdressing sites and their gazillion members who mostly dress for intimate reasons are not really interested in public perception. The public are also not interested in their private proclivities.
Personally, I think y'all need to figure out who you're representing before starting this cause, because if ALL crossdressers literally walked out of their closets as suggested here, you might find public perception worsens. While the members on this forum all appear on similiar paths, I wonder about your commonality with the other sites. Are you really a group with a common cause, or a very diverse collection of people who just happen to wear women's clothing?
