I personally sent my own kids to a private religious school when they were young, and I wouldn't recommend it either today as a general option. In developing nations, schools run by religious organisations are often the ONLY option for many people, especially those from the less privileged masses, who are poor. Secular education provided by schools with a religious background are often top-notch and the best in a city or area. In Kathmandu, one of the private colleges run by the Jesuite order and providing tertiary-level education, is in high demand and has a high reputation. The same for certain schools all over Africa.

With that being said, I think you should refrain from telling anyone which schools h/she should send his/her kids to. You are the least one to provide good advice in this respect.

And because of your belief, you are planning to send Esther to a religious private school for girls only, on the shore of some remote area. Shame on you, Taffy. That was good in the Victorian times; no longer good. Even bad. Shame shame
