I have been a practicing Catholic all my life. I have been involved in several different parishes since my teens. I am married to a Catholic, I have friends and co-workers who are Catholic and I send my son to a Catholic school. My city is culturally Catholic. In short, I have reason to think I have some idea of what Catholics believe and think.
About six years ago I first discovered the internet, and found that internet Catholics seem to bear little resemblance to those I knew in real life. Internet Catholic moms all stayed home, and many homeschooled. IRL, about half the moms I know returned to the work force when their maternity leave was over. All but one of the other half returned when their children started school. The only homeschooler I know IRL only did it for a short time, and I met her on the internet. On the internet, natural family planning is normal. IRL, of reasonably devout Catholics I know well enough to know something about their family planning practices, most have used artificial birth control. On the internet, women priests are an issue--some are very against them, others support those who got themselves "ordained" outside the authority of the Church. IRL, people I know mostly think the rule against women priests is a little old-fashioned, will probably change one day, but isn't anything to get all upset over--or disobey. On the internet, nobody seems to like the music played in the majority of churches--but if nobody likes it, why is it played?
Why do internet Catholics seem so different from IRL Catholics?
