Despite their great PR, their argument has never been very robust. "Pro-lifers" who don't oppose the death penalty or show concern for the poverty that is often the reason for pregnancies to be unwanted. "Defence of marriage" which denies healthy marriage to anyone who's not heterosexual. "Biblical values" which are terribly selective of only the parts of scripture that further their narrow cause. These have always been indications of sly PR that justifies hate and intolerance with Jesus' words, which is a real travesty. But now we can see a blatant evidence that Evangelicals aren't really promoting Christian values as their own narrow, hateful ideology. Christianity is here merely a convenient and honored tradition, used to make this ideology seem legitimate.
A great number of "Christians" seem to ignore much of what Jesus said except for a few choice phrases (Shakespeare reminds us that even "the devil can site scriptures for his purpose"!) The term "Christian" implies those who follow the teachings of Christ. It's not that Jesus didn't say such things as “Do not suppose that I have come to bring peace to the earth. I did not come to bring peace, but a sword.” To some this is a validation of their own desire for violence. But it ignores the REST of Jesus's message, the bulk of which is concern for the poor and dispossessed. There aren't very many groups that have the courage to embrace that kind of idea, so instead lazy "Christians" simply cherry-pick the religion they want and stamp Jesus' logo on it. For shame!
I say if it doesn't show concern for the weak, the poor and the stranger it is NOT CHRISTIAN, regardless of what label is on it. The same is true of any faith that sprouts violence: it is an abberation, not a sacred admonition. That is how to separate the wheat from the chaff. There are slimebags in probably every community. Just because they're loud, don't let them speak for the whole lot!
* Disclaimer: I know that any kind of generalization is always a loose approximation. There are some purely faithful Evangelicals who are as deeply Christian as anyone. No group can accurately be painted with a broad brush. But the group has to take responsibility for their own. I apologize to the world for some "Christian" behavior because they are of my brotherhood. Worthy Evangelicals should do the same, as should any group whose members embarrass us!
