The Pincer Attack
One of the mostly commonly utilized conceptual weapons in the rhetorical attack on being a normal person is ‘sexual fluidity.’
In a nutshell: “Sexual fluidity is one or more changes in sexuality or sexual identity (sometimes known as sexual orientation identity).” It’s a favorite concept among third wave feminists, especially those who argue against hetero-normativity (which is another way of saying, ‘reproductively viable intercourse’). It is especially important to these theorizers because sexual fluidity is allegedly very common among women and therefore central to female experience. I suspect it’s actually common due to the difficulty some feminist theorists have finding partners of the opposite sex.
