No. The issue will fade away - rapidly. It is not like a a bunch of fetuses that some consider the functional equivalent of babies out of the womb, are being offed every day. It is giving the name "marriage" to civil unions (even a majority of Pubbies favor civil unions these days, en route to throwing in the towel on this really), and extending certain federal benefits and duties to them. That is not. It is in actuality, largely a big nothing.
Agree. There will be impotent rage for a while (as there was after Loving v. Virginia), but it will die down within a decade. Think Alberta's reaction to same-sex marriage in Canada.
