It's something fundamental to me, human rights that people are equal under law simply because they are human beings. And I can no more imagine falling in love with someone who believed, for instance, as Orthodox Jews do, that women are unclean during their menstrual periods.

It is easy to forget, since the Catholic Church is now the only large American religious denomination whose ecclesiastical hierarchy continues to oppose birth control, that only a century ago the leaders of nearly all churches were united in their resistance to any public discussion of the subject.

Too many Americans have twisted the sensible right to pursue happiness into the delusion that we are entitled to a guarantee of happiness. If we don't get exactly what we want, we assume someone must be violating our rights. We're no longer willing to write off some of life's disappointments to simple bad luck.

One of the reasons there are largely Catholic and largely Protestant regions of Germany today is that people did sort themselves out geographically.

There could be no more powerful argument against mixing religion and government than the success of independent African American churches in placing racial segregation and discrimination on a reluctant nation's social agenda. Would black churches have been able to take the lead in the struggle had they been dependent on funds doled out for 'faith-based initiatives' . . . ?

If you believe in what I do, which is secular humanism, I would find it extremely difficult to live with someone - not to love someone - but to live with somebody and build a life of someone who disagreed with me on something so fundamental.

I wanted to know how much of conversion was forced - that is, forced in the sense that the Inquisition forced people to choose - forced Jews, let's say, and Muslims to choose conversion to Christianity or death. I wanted to see how much of conversion historically was forced in that way and how much of it was really a kind of persuasion.
