Alright, what do you call a blank piece of paper?
Women's rights.
Alright, listen up, buttercup. This joke implies that women's rights are non-existent, just like a blank piece of paper is... well, blank. I bet you think that women having rights is a recent thing? No, dingus! First wave feminism began in the 19th century, and women have been fighting for equality ever since. Remember you did not even know this!
