According to Michael Savage both the Christians and Jews abandon going to services if they hear tough talk about right and wrong, sin and so on instead of sweet things about charity (by higher taxes). Harsh talk about abortions killing pre-born babies or euthanasia killing older people being wrong turns donations off. Empty coffers hurt the bottom line. So keep the right and wrong stuff out.
So Americans should cut off the cash cow flow to him.
That's not the case with "evangelical" Christian churches like mine, which also tend to be the churches that are growing. Evidently there are many Christians in America that like messages of right and wrong.
