Let's just say your assertion about contraceptive use and abortions among Catholics are accurate. (I have never seen those statistics, but honestly it wouln't surprise me, at least the abortion one)

What does that have to do with the truth or wisdom of a particular teaching? Last time I checked truth wasn't a popularity contest. Look at Christ in John 6.
