Although the current mainstream seems to have endorsed immorality across the board, I think that our relative silence about it is, mostly, frustration about how things like this have been going the last few years. It is my prediction that no serious candidate for President of any party will ever again oppose same-sex marriage, or a host of other moral losses because they will stand no chance of winning.
What I would observe is that the talking that goes on during davening (including by Roshei Yeshiva, etc.) indicates very strongly that we’re not paying the attention we need to to what we say to Hashem. Perhaps it’s mida kneged mida that he’s not paying attention to our lip service for His Torah in regard to the moral issues of our time.
