The pigeons have gotten to your brain! Sola Scriptura is a cathoilic fiction about non-catholics, since the author of the scriptures is active when one reads the scriptures, to edify the reader. And, to astonish everyone, I would ask a similar question to yours, except I wouldn't try to malign protestants in general by claiming 'so many prots want to kill babies': why do so many alive humans want to terminate with extreme prejudice the alive unborn?
You really didn't have to be such a puissant, trying to malign non-catholics, by conflating the murderous evil of abortion supporters with all non-catholics, but of course, that is exactly what you tried to do, in typical holier-than-thou catholic style at FR.
