Well, the world evolved and judging by this thread is it a majority here that still are/want to be stuck in ignoring reasoning needed to evolve to keep up with the world, socially, scientifically and personally. If you don't understand that being labeled "pussy", "bitch" and "acting/throwing/whining like a girl" is using gender as a demeaning label, then ask yourself why you use those words. Though, since that might require some thinking, perhaps just ask yourself if you want to be labelled that way. If you don't want that, then don't label others either.
