They didn't do very well on that one question. Odd that they didn't
mention the scores on the test over all, or any other question, but only
picked that one question, don't you think?
And it's quite a laughable leap to come to this conclusion:
"Is this adequate proof that our attempt to establish "gender equality"
is a failure? Yes."
As they say, figures don't lie, but liars sure can figure, and this
nonsense proves it.

The ass wipes at christianparty.net hate females, and want to rag on
them.
