There are many faults with your backwards thinking but at the most basic is the twisted idea that but for gay marriage we Jews can live comfortably in regular society. Fact is gay marriage or no gay marriage the American POP culture society is no place for raising kids. I am far from being a hareidi but it has now become increasingly clear that exposing our children to what the world has to offer unfettered is a horrible idea.
Instead, we frum Jews should do our jobs raising our kids frum and let gay men and women live their lives without our involvement.
The idea that this is our fight is ludicrous. It is just as stupid as asking America to ban Christianity because it is idol worship.
We have been given the great privilege of living as we choose in this great country. The idea that we can now come to them and say live by our rules is so chutzpadik it is repulsive. Be a liberal or be a conservative or be anything else you want but leave our Torah out of it.
