YES REALLY -you stated as much yourself: "Normal" is just the mean and median of the data points, graphed along a bell curve." Normal people do not express love by engaging in self destructive intrinsically disordered activity...
there is no love test for marriage.
in fact no law has a “love test” (or orgasm test, or happiness test, or god test, or sexual activity test)
this propaganda stunt of ANY two (group?) wanting to live in a “loving committed relationship” is just a fiction created for the weak minded judge.
Believing in a “born gay” gene is akin to the easter bunny or tooth fairy.
