The only data available for the IFB finds that there were 400 instances of abuse across 168 churches over a 40 year period. Let's just assume there are 500 members at each of those churches. So 84,000 people, over a 40 year period, and there were 400 instances of abuse (not forcible rape).
So take 40 years X 84,000 people = 3,360,000 people years. 400 cases of abuse over that period means a percentage of 0.012%.
Each year in America, there are 40 instances of forcible rape (not sexual abuse), per 100K people. That means the percentage of people forcibly raped each year in America is 0.040%.
That means in overall society, you are 3X more likely to be forcibly raped than sexually assaulted at an IFB church. GFY.
