These are legal and political battles that are being decided in the voting booth and the courts, our individual religious beliefs are not enough to fight legalization with.
Most everyone on this forum shares the same religious belief on marriage, but how does telling each other that, help us stop homosexual marriage and polygamy in America?
Well the first thing one ought do before advancing to activism, is to make sure what you believe is correct and ought be applied, and the second thing you should do is to make sure you know how to articulate it to others.
Now, if you have constructive suggestions for activism, I think they will be welcome, but that was not the subject of this particular discussion so far.
