Are these Christians stupid? If they succeed in making it legal to discriminate on religious grounds, it will be perfectly legal (or at least logical) to discriminate against Christians. Why are they taking legal action without thinking the issue through to the next question that naturally occurs, and being appalled by the answer?
Joe, I admire you greatly, but you're wrong on this one. You are promoting legal discrimination. You haven't answered the question about whether or not businesses should be legally permitted to refuse service to black people. Where do you draw the line with discrimination?
