Fears of atheistic authoritarianism aside, some may worry about religious organizations fading away because they do so much good. They do engage in a tremendous amount of charitable work that includes holding food drives and setting up soup kitchens and homeless shelters. However, such welcomed charity is ultimately an altruistic response to symptoms, not a structural cure for root causes.
This is why highly secular democracies do a much better job of ameliorating homelessness and poverty by employing decidedly secular solutions, such as responding with rational social policies and wise economic strategies, and setting up more responsive institutions. Affordable housing and subsidized healthcare do a far better job of alleviating the suffering of the poor and the sick than faith-based charities.
Secularity is highly correlated with a host of moral orientations that will markedly improve our nation. For instance, secular people — when compared to their religious peers — are far more likely to understand and respect the scientific method, which results in their increased willingness to get vaccinated, for instance, and adhere to empirically grounded health recommendations, a rational orientation that saves lives. Secular people are also more supportive of sex education, which reduces unwanted pregnancies and sexually transmitted diseases.
