The 1990s and early 2000s was the golden age of professional Catholic apologetics. If you wanted to get schooled about apologetics, you tuned into the Catholic Answers Live every afternoon. You read the tracts of Mark Shea, Karl Keating, and Jimmy Akin. You listened to the Al Kresta Show syndicated through Ave Maria Radio. You watched Fr. Mitch Pacwa on EWTN and owned sets of Fr. John Corapi's lectures on cassette. You probably owned several books and VHS tapes by Dr. Scott Hahn. These professional defenders of Catholic truth were the resources to turn to when you wanted to learn how to respond to objections to the faith, especially those leveled by evangelical Protestants.
Those who have gone down this path—and admittedly, it is not all, but still a fair amount—have fallen in the same pit that many have today, which is to assume one's positions are so secure, so unassailable, so self-evident, that those who disagree with you are not simply mistaken, but are morally bad. As someone who formerly admired and learned from these people, it has been extraordinarily disappointing to see them behaving like the worst of the blue checkmarks. I'm not calling anybody out by name, but we have all seen them lurking around in comboxes and Twitter feeds and Facebook threads, spitefully belittling people whose only offense has been to disagree.
Whatever it's cause, it is clear that the age of pop-apologetics is over.
