So, the strategy chosen by 1980s gay men seems to have paid off in producing a more rational discussion.
You haven't shown this. You've shown it achieved their aims, so might have been instrumentally rational for them, and that it was vindicated by subsequent value change/drift, but not that the new discourse is more rational. It can be instrumentally a good idea to make discourse more irrational in some specific way, or to change others' values, against their will.
I was assuming that everyone agreed that the 1980s discourse about homosexuality was nuts, since it was strongly influenced by Christianity -- I guess if you take Christianity seriously, we would need to have a different discussion, but the assumption is that almost nobody here does.

It seems like a very useful dichotomy, and strongly reminds me of Ask and Guess.
