Logic
Reductio ad absurdum is a useful tool for testing the truth (correspondence to reality) of a premise by seeing if it's true in all cases. However it's also just that, a tool. Logically an argument can be valid (arguments should be valid, premises true and terms clear) if the claim is that 'gender and sexuality should be ordered a certain way.' Firstly, there is no contradiction if an exception is found, for example gay dolphins or consenting adults; because the original argument is contingent, gender and sexuality should be ordered a certain way. But secondly it's a fallacy to say 'gender and sexuality are whatever we want them to be because of those examples', that's making a inductive claim about the whole world based on a limited set of exceptions, an argument from selective observation.
Gender
At the moment it's very controversial to link a discussion of gender to the male and female sex organs. This isn't say that the expression of gender is cultural; with lots of regional variation but nonetheless the categories exist and Scripture wants us to affirm the cultural expression of distinct genders. In other words the Christian claim is that God made genetic gender differences and the cultural differences which flow from those genetic distinctions. Regional cultural variations, ambiguous gender at birth and variations in your internal sense of gender are not in of themselves logical arguments against affirming gender distinctions.
Sex
Sexual activity, like all of ordinary life has an existential effect on our psyche but like other ordinary activities (such as eating or travelling) shouldn't be the source of our identity. The essence of being human isn't our rationality, appetites, appearance or our sexuality. There are a range of sexual activities, desires and situations that we have access to; that's why those Old Testament laws focus on sex acts and not on sexuality. This is also why "same-sex attraction" is a more accurate term than "homosexuality", which seems to mean a certain set of cross-gender behaviours.
Culture
So the front man of Jars of Clay has come out in support of same-sex marriage, you can read out it here. My knowledge of the Christian music genre is limited, but for me they represented the archetypal Christian-band. After the Enlightenment, it seemed the world was divided between the real rational stuff and the esoteric irrational stuff, with the history of philosophy since then defending the primacy of one or the other. The variety of relationships between Gospel and Culture are often an echo of this philosophical history. Jars of Clay represented the impulse to Christianise certain aspects of the real rational world, 'see Christ does speak to the real world, this is a Christian pop-band.' I think this Jars of Clay thing signals the end of that particular approach to Christ and Culture.
