'National Association for Single Sex Public Education'. Who knew?!

I cant believe there is a National Association for Single Sex Public Education. The N-A-S-S-P-E. I am sceptical of any 'EVIDENCE' that is being presented in this argument by the NASSPE. Considering the source, I am not sure about the equal representation of an opposing view point. Interesting though....it's a pretty thorough website. I can't believe I never heard of this organization before.   http://www.singlesexschools.org/
