How does that prove that men are "easier" than women? It only indicates that within Okcupid's membership, men are more likely to initiate communication with a potential partner. Perhaps women are no more selective than men, but simply typically prefer for men to initiate the conversation, as your parent post claims.
Okcupid has the data, and men are more likely to message women than vice versa. Whether or not it's innate is irrelevant to this conversation.
But since you like anecdotal evidence so much, here: http://www.wetherobots.com/comics/2008-01-07-Misinformed.jpg
