First, it denigrates the Bible, a document that has successfully guided believers into better behavior and outcomes for millennia. For every bad action, and there are plenty, performed by 'believers', you can find specifics in the Bible that they have violated and you can find where true believers have done good actions. As a civilizing force, it is hard to compare Judeo-Christianity with any other pagan or religion and not come away with a favorable opinion of the former.
Second, I have tried to come up with a counter pejorative to "bible thumping" and just failed. Our popular culture of today is pervasively anti-Christian! This is almost unreal but I think that we have never had such a corrosive entertainment and media establishment that is so anti-Christian. Just witness the denigration of Tim Tebow by his critics as a single example. Whether you chalk it up to the 60-70s radicals, the liberal mindset or the propensity of the GLBT crowd to enter this field as a profession, this industry does not consider traditional Judeo-Christianity as a "Good Thing" and desires to attack it whenever possible.
I know not the answer, but trust in God while I fight all of these pernicious and ultimately deadly attacks.
I’m going today. Someone told me it won’t be very busy on Sunday.
This is a joke. Please don’t send me dozens of messages telling me that they are not open on Sunday.
