Almost nobody, myself included, believes this is a result of discrimination against Protestants. 2% of the population holding 33% of the seats, and 25% of the population filling the rest.
But whenever similar disparities appear in other areas, the default assumption is that illegal/immoral discrimination can be the only possible explanation.
I agree.
Too many educated, achieving-class protestants (and their mainline churches) have left the conservative reservation for an equal demographic distribution to likely occur by happenstance.
And I’m a fan of happenstance.
