Social movement scholarship claims that opposing movements can create oppor
tunities and generate mobilization for the other side, However, there are s
till open questions as to how this influence between opposing movements ope
rates on an organizational level. This paper looks closely at one aspect of
the impact of opposing movements: rhetorical strategies. I examine histori
cal documents produced by social movement organizations to determine the pr
ocesses through which interactions between opposing movements are integrate
d into the everyday work of producing movement claims, This historical anal
ysis evaluates the flyers, newsletters, and press releases of lesbian and g
ay movement organizations in the United States over time, comparing documen
ts produced before the emergence of the Christian anti-gay counter movement
in 1977, with those produced immediately following the counter movement's
entry into the political scene. I analyze the shifts in lesbian and gay act
ivists' claims between these two brief time periods and link these changes
to the presence of Christian anti-gay activists. I find that frames, tone,
and language shift for issues that were directly addressed by the Christian
anti-gay movement (lesbian and gay rights), but that no similar change tva
s present for issues on which the anti-gay movement remained silent (police
harassment and lesbian/gay media representations). These findings support
the claim that opposing movements alter the political context in which the
other side works, but they also demonstrate that new opportunities produced
by an opposing movement may be issue-specific rather than movement-wide.
