Resist we much......!
Many years ago my father and I had a talk about Judaism. He told me there was one way to wipe out the Jews and Israel; leave them alone. They would marry out of their faith and over several generations, except for the ultraorthodox, they would become secular.
While I am not comparing Jews to gays, my point is, if we just ignore the gays, they will quietly live out their lives and die without offspring. If we focus on raising our children in a traditional Judeo/Christian environment, despite what the left does, eventually the hoopla will die down and this whole gay chic lifestyle will fade away.
My college age son and I had this discussion and I asked him about why there are so many gay kids in high school and college. (my son is straight) He said it was the new rebellion. Because there is so much attention, it is their 15 minutes.
