How about because over 60% of the population identify as a denomination of Christianity, Catholic being the most. Or the importance of having choice for your children's education? Or how about acknowledging the values and the integrity that a religious upbringing can instill in kids. Christianity contains many of the individual values that make up our cumulative values, the 10 commandments for example. If there is demand for Catholic schools, or even just the choice, and clearly there is demand for both, then why should resentful, leftist centralized decision makers be able to simply remove the choice? Honestly, the arrogance and closed mindedness socialism of the left blows me away.
