History of Catholic schools public schools anti-catholicism
Those are pretty weak supports for your contention that the establishment of public education in the United States was for the purpose to *de-Catholicize Catholics*.
I’m calling BS on that whole conspiracy theory. Unless you can provide any substantial evidence to support that contention any more, I’m going to start hitting the abuse button every time I see someone trying to stir the Catholic Protestant pot by bringing up questionable events and accusations of things that happened over a century ago.
Implication and innuendo do not make a case.
