Historically, in the US, 19% of the credible, reported abuse of minors by clergy were girls (John Jay College of Criminal Justice Report).  Nineteen percent is not a trivial fraction to  ignore.  Apparently, in Latin America, the percentage of female victims could be higher because of a lack of reporting; we may never know. But in any event, in the US, 1 out of 5 victims was female. Your fix, would not have prevented prevented that abuse. Nor would you fix have prevented  Shawn Ratigan, a priest in KC or Joel Wright, then a seminarian at Josephinum, from causing harm as reported in the news of recent times. Maybe only accepting eunuchs for ordination would make all these problems disappear, but of course, my suggested fix should be clearly rejected by all as a simpleton's solution for a complex problem.
