His point was not to point out her lofty view of herself. His point was to imply that she is the person who would be so ridiculous as to change her gender only in order to compete in pool tournaments. There is a huge difference between the two. I am not the type who is always offended, only when things are truly offensive in nature.

This is what is truly offensive
