From the Los Angeles Times:
That a particular social change may be inevitable, given certain background conditions, does not mean that opponents will cease fighting it. White Southerners continued to massively resist Brown long after most of them came to believe that school desegregation was inevitable. Similarly, those who believe that gay marriage contravenes God’s will are not likely to stop fighting it simply because their prospects of success are diminishing. Moreover, because religious conservatives are both intensely opposed to gay marriage and highly mobilized politically, they are likely for the next several years to continue exerting significant influence over Republican politicians who need their support to win primary elections. Although the ultimate outcome of the contest over gay marriage no longer seems in doubt, plenty of fighting remains until that battle is over.
