It seems like a very useful dichotomy, and strongly reminds me of Ask and Guess.
You seem to believe that such a cost-benefit analysis is possible when there is a level of bias that is that pervasive. It is often not possible. The full costs will simply never be recognized. The US court system is supposed to work on the adversarial model, and yet only one non-Christian group has ever won a free exercise clause case at the Supreme Court. Why would anyone play a basketball game when they're sure the refs are crooked?
The number that the 1980s American public would put on a gay man's freedom of movement, is much less the number that the 2012 public would put on that same man's freedom. That difference is, at least in large part, caused by the strategy chosen by 1980s gay men. It's hard to argue that the 1980s number is more likely to be correct, given the high level of bias in the 1980s (see the GSS for details on this bias). So, the strategy chosen by 1980s gay men seems to have paid off in producing a more rational discussion.
In favor of the "sport" decision is that it uses rational-sounding terms like "cost-benefit analysis". But using rational-sounding terms does not actually make any guarantee of 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.
