As the video points out, Christians are delusional. How does the delusion affect Christians in their everyday lives? Here is one example:
New Bank Rules Sink Stocks
If accepted by Congress, the Obama proposals could force significant changes in how the nation’s biggest banks do business. The specter of new profit-crimping regulation battered bank stocks Thursday, dragging down the Dow Jones Industrial Average by 213.27 points, or 2%, to 10389.88. Some financial stocks sank by more than 5%, though they recovered slightly after Barney Frank, the Massachusetts Democrat who is chairman of the House Financial Services Committee, said the new rules would take effect over three to five years, not immediately. J.P. Morgan Chase & Co.’s stock was the hardest hit, sinking 6.6%.
The concept that the Wall Street Journal is espousing in the article is simple: What Obama says and does has immediate, dramatic impacts on the market; there is a direct cause-effect relationship between Obama and the stock market.
The problem is that, as soon as you accept that concept, then you have to explain this graph showing the dramatic rise in the stock market in 2009:

If Obama is to blame for the drop in the stock market last week, then he is also to blame for the 10-month rise, is he not?
When questioned about this, the WSJ would surely say, “There are other explanations for the rise in the stock market over the last year - Obama had nothing to do with those stock market increases.” In other words, Obama is the direct cause of all stock market drops, but none of its increases.
What does this remind you of? It is just like the Christian belief that God causes all blessings, but none of the disasters. “Praise God from whom all blessings flow”, and all that.
Both of these beliefs - 1) that God causes all (and only) blessings, and 2) that Obama causes all (and only) stock market drops - are completely delusional. No rational person would tolerate such cognitive dissonance in his or her thinking. But for Christians, because they are delusional to begin with, such dissonance is easy to accept. They embrace massive dissonance every single day in order to be Christians.
Daniel Dennett puts it this way in Problem of evil and religion’s double standard:
The idea that God is a worthy recipient of our gratitude for the blessings of life but should not be held accountable for the disasters is a transparently disingenuous innovation of the theologians.
Religion is delusion. That delusion has a negative impact on the thinking of all religious adherents because it encourages them to be delusional in other parts of their lives as well.
